Introduction

The lateen sail is a triangular sail on a long yard mounted at an angle on the mast, running in a fore-and-aft direction. It is common in the Mediterranean, the Indian Ocean and the Red Sea

Lateen Sail Is Fun But Here’s What You Need To Know: A blog about lateen sails and why they are awesome.

There are many reasons to love the lateen sail. First, it is an efficient sail shape that you can use for almost any type of sailing adventure. In addition, the design allows the boat to be easily controlled in different winds and waves by simply changing the angle of the sail. Finally, this shape allows you to set up your boat faster than other types of sails because there are fewer pieces involved!

A lateen or latin sail is a triangular sail set on a long yard mounted at an angle on the mast, running in a fore-and-aft direction.

A latin or lateen sail is a triangular sail set on a long yard mounted at an angle on the mast, running in a fore-and-aft direction. The sail derives its name from its shape which is similar to that of an equilateral triangle. In some texts it may be referred to as a latten sail (or latin) due to the material from which it was traditionally made.[1]

The triangular shape allows the sheeting angle of the attached spar to vary continuously along its length; this allows for greater control of sailing performance than if it were fixed at only one point along the mast.[2] A pair of such sails form one unit called thus: “two sails” would be two units and so on.

The earliest known depiction of an Egyptian vessel with such sails comes from an bas relief dating back as far as 1250 BC.[4] This relief shows an early example where two men are operating each side of these fore-and-aft rigged vessels, both equipped with long sticks used for steering and sailing.[5][6]

The lateen evolved out of the square rigged tanja sail, used by the Arabs and Greeks to reach East Africa and the Indian Ocean.

The lateen sail evolved out of the square rigged tanja sail, used by the Arabs and Greeks to reach East Africa and the Indian Ocean.

The tanja sail consisted of a square-shaped sail with its yard hung from a long spar called a boom. The boom was either attached to or parallel to the mast, depending on whether it was held away from or towards the centerline of the boat.

The modern Arab dhow is still rigged with one or two lateens, while most other boats use a fore and aft sloop rig, sometimes with a jib.

The main advantage of the lateen rig is that it allows the sail to be flown from a short mast and yet keep its shape and not collapse as happens with most other rigs. Because this sailboat has a triangular sail, it is also easier to tack when sailing in light winds.

Lateen sails are easy for one person to handle, so they are usually used on small boats by people who don’t want their boats to be too big or complicated. They are also good for sailing in shallow waters because the boat can get closer to shore than other types of boats can.

Lateens were also used on Roman ships to round the Iberian peninsula.

According to Encyclopedia Brittanica, the Romans used lateens on their ships to sail around the Iberian peninsula. This was incredibly important because they were able to conquer Spain using these ships.

However, while lateen sails are quite useful when it comes to maneuverability, they aren’t very effective at powering a large ship through rough water. Because of this limitation and other factors such as weight distribution and sail area ratio (the amount of surface area covered by the front of a given sail compared with its height), Roman war galleys didn’t use lateen sails.

From the beginning of the 12th century, as trade flourished between Egypt and India, the lateen gradually came into use in the Mediterranean.

The lateen sail was introduced to the Mediterranean in the 12th century, as trade flourished between Egypt and India. It was used for sailing on Arab dhows and Roman ships, which were usually merchant vessels.

The lateen sail is also known as the triangular sail because of its shape—a long triangle that makes up one side of a sailboat. This type of sail has been used in China since at least as far back as 700 B.C., but it didn’t become popular until after being adopted by Arab sailors during their voyages around Africa and into Asia in search of spices.

The Chinese junks have a hybrid rigging – with a forward-facing boom-rigged mainmast with one or more lugsails, and one or more lugsails on each side of the mizzen mast.

The Chinese junks have a hybrid rigging – with a forward-facing boom-rigged mainmast with one or more lugsails, and one or more lugsails on each side of the mizzen mast. The foremasts are usually rigged with junk sails, while the after mast may carry either square-rigged or junk gear.

Sail Types: A Comprehensive Guide to 8 Types of Sails

Sailboats come in all shapes and sizes. And that means there are many types of sails on the market! For those who might not know, sails are made of canvas and use wind power to propel sailboats through the water.

Understandably, different sails are required for different types of sailboats . And sailboats are categorized by the number of hulls they have. Monohulls have a single-hull design, catamarans have two hulls, and trimarans have three. Generally, sailors use catamarans for upwind sailing (but they can be used to sail downwind in certain conditions).

The type of sail you'll need for your sailboat depends on the kind of sailboat you have. Additionally, sails are highly dependent on the wind and weather conditions. Therefore, it's always a good idea to have different types of sails on board to navigate the ever-changing weather conditions.

8 Types of Sails for Sailboats

As mentioned, you should carry multiple sails when sailing to prepare for various weather conditions. Here's a brief overview of the types of sails for sailboats:

1. Mainsails

The mainsail is the largest and most important sail. Therefore, it's probably the first sail to come to mind when you think of camping. Typically, it's situated directly behind the mast — connected to the boom — and uses wind energy to move the vessel. The mainsail plays a significant role in tacking and gybing, making it essential for any voyage.

Since the mainsail is a larger sail, it doesn't require wind to propel it forward. And the fact that it can be moved by moving the boom makes it uber-easy to operate.

2. Headsail

The headsail often accompanies the mainsail, though it is smaller in size. Regardless of your sailboat type, the headsail is positioned at the front of the mast – over the sailboat's bow.

Because headsails are small, they are helpful when navigating through windy conditions. Smaller sails catch less wind, preventing them from propelling your boat as strongly as larger sails. Additionally, headsails help lift, balance, and protect the vessel from inclement weather conditions.

While the term 'headsail' refers to any sail in front of the mast, the jib is the most common type of headsail. (And when a jib is so large that it overlaps the mast, it's called a genoa.)

3. Genoa

The genoa is a large sail that attaches to the front of the forestay. (In this instance, it's similar to a headsail.) However, the genoa is larger than the headsail and overlaps the mainsail partially or completely to help the boat go faster.

Genoa sails are useful when sailing through light or medium wind. You can also use it when the wind comes directly from the rear. If you use a Genoa sail during high winds, you'll probably start sailing too quickly and put yourself and your boat at risk.

4. Spinnaker

The spinnaker is a large and whimsical (often colorful) sail. Spinnaker sails are usually symmetrical, allowing them to reach different points of sail. Generally, these are lighter sails and don't cover the mast like the genoa.

Because spinnaker sails are on the larger side, you have to be incredibly careful with them. Don't use them in rough conditions. Instead, save them for sailing in low winds and calm seas.

5. Gennaker

As the name suggests, the Gennaker sail combines a spinnaker and a Genoa sail. They are as large as the spinnaker, although they're not symmetrical.

They come in handy whenever the wind changes from a pure dead run to a reaching point of sail, as sailors can navigate various wind types with the same sail. It's still only meant for lighter and milder winds, but it's more versatile than the spinnaker and genoa.

6. Light Air Sails

Light air sails are useful in calmer conditions when the headsail and mainsail alone aren't cutting it. They include:

Code Zero : A code zero sail is a gennaker sail ideal for sailing in light to mild winds. It's designed to create lift and boost boat speed whenever regular sails don't generate enough power. For that reason, many racers and cruisers use code zero sails to improve performance and gain control in various situations.
Windseeker : This small, special sail is reserved for no wind or light wind. Essentially, it helps boats remain maneuverable in extremely calm conditions. And for that reason, it's valuable to long-distance sailors.

7. Storm Jib

Storm jibs can be used as a headsail whenever the weather is particularly rough and windy. Because it functions as a safety seal, it prevents boats from capsizing by reducing the sail area exposed to the wind. Therefore, it's a necessary sail for every sailor.

The Definition And History Of The Lateen (Triangular) Sail

Sailing, as we know it today, has been shaped by many developments and innovations throughout history. One of the most significant inventions that has helped to make sailing the sport it is today is the lateen sail.

The lateen sail is identifiable by its triangular shape (see also ‘ Why Are Sails Made In A Triangular Shape? ‘) with a sloping yard that is longer than the other sides of the sail.

These days, lateen sails (or the modernized versions, at least) are commonplace, but what exactly are they and how were they developed? That’s what we’re going to be exploring in today’s article.

What Is The Lateen Sail?

As previously mentioned, the lateen sail is a triangular sail where one side is secured to a sloping yard by each of its two corners. The third corner of the sail is secured to the sailboat close to the deck.

Lateen sails, unlike some other sails, are mounted towards the middle of the mast, and the direction the sail runs in is known as ‘fore and aft’, which means that it runs both forwards and backwards, allowing it to withstand wind from both sides of the vessel.

Eventually, the lateen sail would be designed to allow ships using it to sail into the wind which, as we will find out over the course of this article, was instrumental in revolutionizing sailing.

If you were wondering where the word ‘lateen’ comes from, it’s actually derived from ‘Latin’.

The reason for this is that the lateen sail’s origins have been pinpointed to the Mediterranean during the Roman era, although the invention really came into its own during the Age of Discovery.

At the beginning of this article, we touched on the fact that the lateen sail is still used today. However, the version you’ll see on modern sailboats in the 21st century are modernized versions of the original design, known as crab claw sails.

We’ll be going into more detail about this later. For now, though, let’s explore the history of the lateen sail from the Roman era to the 14th century and beyond.

The Lateen Sail’s History

The roman empire .

If you’ve read through the article so far, you’ll already know that the lateen sail dates back to the Roman Empire.

The lateen sail’s history actually begins with another kind of sail called the square sail rig. This is a type of rigging where multiple sails are mounted to a ship using horizontal spars. This was the design that inspired the evolution of the lateen rig.

For a long time, it was unclear when exactly the lateen sail dated back to.

That was until a Belgian maritime historian named Lucian Basch pointed out that a Hellenistic painting from Alexandria dated at roughly the 1st century BC actually features a lateen rig, indicating that the lateen sail’s evolution dates back to at least this period in history.

A lateen sail ship from roughly the year 400 AD has also been excavated, and the experts that helped to reconstruct the ship have stated that it’s likely the lateen sail’s existence extends further back than historical documentation would imply.

It is now thought that the lateen sail was actually developed by Muslim-led fleets before it began to be used in the Mediterranean.

The 6th – 10th Centuries

Until the 6th century AD, the square sail was the standard for sailors, hence the identification of the square sail rig as the starting point of the evolution of the lateen sail.

However, by the end of the 6th century, the lateen sail had been established as the most effective type of sail, and it had almost completely replaced the original square sail, at least in the Mediterranean.

The Byzantine dromon war gallery used the lateen sail as well, and considering that this ship has been hailed as the warship of greatest significance throughout the whole of the Byzantine period, this goes to show what an important innovation the lateen sail was.

Various different navies around the world began using the lateen sail between the 6th century and the 10th century as the popularity of the hook-shaped masthead began to increase, showing that the lateen sail’s efficiency and benefits for sailing were beginning to become common knowledge.

The 14th Century Onwards

After the 14th century, the lateen sail continued to become established throughout the world. Baltic and Atlantic sailing vessels started using the lateen sail rather than the square sail from the 14th century onwards.

During the late Middle Ages, the lateen sail became commonplace in Northern Europe as well.

Contributions Of The Lateen Sail

In the section above, we covered how the lateen sail evolved out of the square sail rig and spread throughout the world between the Roman era and the Middle Ages.

However, we haven’t yet covered the reasons behind the massive surge in the popularity of the lateen sail and why it eventually replaced the square sail in navies worldwide.

Here are some of the main reasons for the lateen sail’s popularity in terms of what this sail design contributed to sailing as a whole:

Better Maneuverability

One of the biggest advantages of the lateen sail over other sail designs, including the square sail rig, is that it allows for greater maneuverability.

Being able to maneuver a ship efficiently, especially in challenging weather conditions, is extremely important, and so a sail’s ability to facilitate this is crucial.

Part of the reason why lateen sails made maneuverability easier is that they allowed ships to sail closer to the wind, which meant that weather conditions were less of a problem when it came to altering the course of a ship.

However, more than that, lateen sails also operated using a pulley or block system known as a halyard system, where lines run through the sail starting at the stern and going all the way up the mast and down to the stern again.

Halyard systems were instrumental in allowing reefing, which is where the sail area is made smaller to reduce the power during strong winds. This made the experience of sailing much more flexible and safer overall.

More Speed

Lateen sails allowed ships to travel faster than the previous square sail rig design had done, especially in the case of Caravel ships.

The faster speeds achieved by Caravel ships using lateen sails made excursions and explorations much easier and quicker. Sometimes, the lateen sail would be combined with the square sail, as Columbus did when crossing the Atlantic.

Greater Load Bearing

We mentioned earlier that lateen sails improved the maneuverability of ships, but this had more benefits than simply making it easier to steer.

One of the biggest advantages of the increased maneuverability provided by the lateen sail was that ships were now able to carry more cargo.

When you think about it, this makes a lot of sense. Before the lateen sail, ships did not have as much flexibility when it came to changing speed or course.

This meant that in order to maximize the maneuverability of a ship, the crew would have to minimize the amount of cargo on board to ensure that the ship was as light as possible for the rowers.

With the advent of the lateen sail, heavier cargo was able to be transported since the rowing ability of the crew was no longer the main factor.

Not only did this mean that ships could transport more food and other necessities during excursions, but it was also a major step forward for commercial empires such as Venice.

Venice was able to become hugely successful as a European commercial empire because its use of lateen sail ships allowed for the transportation of products throughout the Mediterranean.

Designed For Longer Distances

Part of the reasoning behind the design of the lateen sail was that it allowed ships to travel longer distances since it meant that ships could sail closer to the wind and at faster speeds.

In fact, countries such as Spain and Portugal relied on sea travel over long distances to increase their national statuses, and the lateen sail was an instrumental part of this.

Spanish and Portuguese ships would travel long distances to other countries so that they could trade goods from those countries and build status as a result.

Enabled Land Discovery

We just discussed how the lateen sail’s increased speed and maneuverability allowed for travel by ship over longer distances, and how this allowed countries to build national status and grow through trade.

However, this new ability to travel greater distances also enabled the discovery of countries and lands that had not yet been explored.

This is one of the main ways in which the lateen sail contributed to what is now known as the Age of Exploration, between the 1400s and 1600s.

This period of history is called the Age of Exploration because this is the period in which nations throughout Europe began to use ships to go on excursions and explore the rest of the world, which is what led to the discovery of countries in the Far East as well as the Americas.

Developments In Warfare

In addition to land discovery, the benefits of the lateen sail that we have described so far (speed, maneuverability, load bearing and distance travel) all helped to create developments in the field of naval warfare.

Naval ships needed to bring more supplies if they were going to war because it was unclear how long the ship would be at sea, so the ability to carry more was of the utmost importance.

Lateen sails were also able to improve the maneuverability and speeds of larger, heavier ships with cannons on board, which was why the Dutch, Spanish, French and English all used lateen sails for their fleets during the 19th century.

This had a significant impact on the balance of political power during the Crusades.

The Modernization Of The Lateen Sail

The crab claw sail .

We’ve already mentioned that while the lateen sail is still around today, it’s been modernized since its invention and is now usually known by a different name: the crab claw sail.

It’s called the crab claw sail because it has a spar along the foot of the sail. This spar is aligned horizontally and connects to the mast. The joints in the sail spars have been designed to rotate in every direction for maximum flexibility.

With this design, the sail sheet is connected to the spar at the bottom while the halyard connects to the spar at the top. The bottom spars stay parallel to the mast so that the sail forms a cone-shaped triangle.

The Sunfish Sailboat

Another difference between the lateen sail now compared to centuries ago is that lateen sails are now mainly used in smaller sailboats, typically those classified as recreational sailboats.

Probably the most common example of a lateen sailboat in the modern day is the Sunfish, which is an individual-sized sailboat designed for personal use.

The modernized lateen sail on the Sunfish sailboat is attached to the mast and works using just one halyard, two lines, and of course, the sail sheet.

These smaller, modern lateen sails are easy to work with and can be adjusted using a third line. This line can be used to pull on the lower spar so that it does down, creating tension in the other spars and allowing more control over the movements and positioning of the sail.

Final Thoughts

The lateen sail has a fascinating history that spans from before the Roman Empire through the Middle Ages into the 19th century and, eventually, the modern day.

This triangular sail revolutionized exploration, trading, and naval warfare by providing better speed, maneuverability, load bearing, and distance.

Countries were able to establish themselves and build status by fitting their fleets with lateen sails, and the use of these sails led to some of the greatest discoveries in history.

Today, the lateen sail is better known as the crab claw sail and is used recreationally for smaller sailboats because of the simplicity and ease of use of its design.

Why Are Sails Made In A Triangular Shape?

The different types of sails and their uses

Discover the different types of sails and their uses to optimize your sailing performance and enjoy the freedom and fulfillment of exploring the open sea.

The Different Types of Sails and Their Uses

Sailing is an incredible way to explore the world, spend quality time with family, and embrace the freedom of the open sea. As you embark on your sailing adventure, it’s essential to understand the different types of sails and their uses. This comprehensive guide will provide you with the knowledge you need to navigate your journey confidently.

Introduction to sails, symmetrical spinnakers, asymmetrical spinnakers, sail materials and construction.

Sails are the driving force behind any sailing vessel, harnessing the power of the wind to propel the boat forward. They come in various shapes, sizes, and materials, each designed for specific sailing conditions and purposes. Understanding the different types of sails and their uses will help you make informed decisions when selecting sails for your boat and optimizing your sailing performance.

The mainsail is the primary sail on a sailing vessel and is typically hoisted on the aft side of the mast. It is a triangular sail with its leading edge (or luff) attached to the mast and its foot running along the boom. Mainsails are essential for providing the boat with forward propulsion and play a significant role in steering and balancing the vessel.

There are two primary types of mainsails: full-batten and partial-batten. Full-batten mainsails have horizontal battens that run the entire width of the sail, providing additional support and shape. Partial-batten mainsails have shorter battens that only extend partway across the sail. Full-batten mainsails tend to hold their shape better and last longer, while partial-batten mainsails are lighter and easier to handle.

Headsails are sails that are set forward of the mast and are used in conjunction with the mainsail to provide additional propulsion and balance. There are several types of headsails, each with its unique characteristics and uses.

A jib is a triangular sail that is set forward of the mast and is attached to the forestay, a wire that runs from the masthead to the bow of the boat. Jibs come in various sizes, with smaller jibs being more suitable for strong winds and larger jibs providing more power in light wind conditions. Jibs are essential for upwind sailing, as they help to direct the airflow around the mainsail, increasing its efficiency.

A genoa is a type of jib that is larger than a standard jib, extending past the mast and overlapping the mainsail. Genoas are designed to provide maximum sail area and power in light to moderate wind conditions. They are particularly useful for upwind sailing, as their large size helps to generate more lift and drive the boat forward. However, genoas can be more challenging to handle than smaller jibs, especially in strong winds or when tacking.

Spinnakers are large, lightweight sails designed for downwind sailing. They are typically set forward of the jib and are not attached to the forestay. Instead, they are held out by a pole called a spinnaker pole, which is attached to the mast and the sail’s clew (the lower aft corner of the sail). Spinnakers are used to catch the wind from behind, providing significant power and speed when sailing downwind.

A gennaker, also known as a cruising spinnaker or code zero, is a hybrid sail that combines the characteristics of a genoa and a spinnaker. Gennakers are designed for reaching and downwind sailing and are typically set on a furling system, making them easier to handle than traditional spinnakers. They provide more power than a genoa in light wind conditions and are more stable and easier to control than a spinnaker.

Downwind Sails

Downwind sails are designed specifically for sailing with the wind coming from behind the boat. These sails are typically larger and lighter than upwind sails, allowing them to catch more wind and generate more power. There are two main types of downwind sails: symmetrical spinnakers and asymmetrical spinnakers.

Symmetrical spinnakers are large, balloon-shaped sails that are designed for sailing directly downwind. They are symmetrical in shape, with the sail’s centerline running vertically down the middle of the sail. Symmetrical spinnakers are held out by a spinnaker pole, which is attached to the mast and the sail’s clew. This allows the sail to catch the wind from behind, providing maximum power and speed when sailing downwind.

Asymmetrical spinnakers, also known as gennakers or A-sails, are designed for reaching and downwind sailing at angles that are not directly downwind. They are asymmetrical in shape, with a longer luff (leading edge) and a shorter leech (trailing edge). Asymmetrical spinnakers are typically set on a furling system and do not require a spinnaker pole, making them easier to handle than symmetrical spinnakers. They provide more power and stability than a genoa in light wind conditions and are more versatile than a symmetrical spinnaker.

Storm Sails

Storm sails are small, heavy-duty sails designed for use in extreme weather conditions. They are used to replace the standard sails when the wind is too strong, providing better control and reducing the risk of damage to the boat and its rigging. There are two main types of storm sails: storm jibs and trysails.

A storm jib is a small, heavy-duty jib that is used in place of the standard jib in strong winds. It is typically set on the inner forestay, closer to the mast, providing better balance and control. Storm jibs are designed to withstand high wind loads and are made from durable materials, such as heavy-duty Dacron or laminate fabrics.

A trysail, also known as a storm trysail or storm mainsail, is a small, heavy-duty sail that is used in place of the standard mainsail in extreme weather conditions. It is typically set on a separate track on the mast, allowing it to be hoisted independently of the mainsail. Trysails are designed to provide better control and balance in strong winds and are made from durable materials, such as heavy-duty Dacron or laminate fabrics.

Sails are made from various materials, each with its unique characteristics and performance attributes. The most common sail materials include Dacron, laminate fabrics, and high-performance fibers, such as carbon and aramid.

Dacron is a durable, low-stretch polyester fabric that is widely used for cruising sails. It is relatively inexpensive and provides good performance in a wide range of conditions. Laminate fabrics are made by sandwiching layers of polyester or high-performance fibers between layers of Mylar film. These sails are lighter and more resistant to stretch than Dacron sails, providing better performance and shape retention. High-performance fibers, such as carbon and aramid, are used in racing sails and offer the highest levels of strength, durability, and performance.

Sail construction techniques also play a significant role in the performance and durability of a sail. Cross-cut sails are made from panels of fabric that are sewn together horizontally, following the natural lines of the fabric’s weave. This construction method is relatively simple and inexpensive but can result in a sail that is more prone to stretch and distortion. Radial-cut sails are made from panels of fabric that radiate out from the corners of the sail, distributing the loads more evenly and providing better shape retention and performance.

Understanding the different types of sails and their uses is essential for any sailor looking to optimize their sailing performance and enjoyment. By selecting the appropriate sails for your boat and the conditions you’ll be sailing in, you’ll be better prepared to navigate the open sea and embrace the freedom and fulfillment that comes from choosing an unconventional path.

The Most Popular Types Of Sails On A Sailboat

A sloop-rigged sailboat typically features a mainsail, a headsail, and an additional light-wind sail, such as a spinnaker or Gennaker. The mainsail is rigged aft of the mast, while the headsail is attached to the forestay. The two most commonly used headsails are the Genoa and Jib.

The sails are vital parts of a sailboat since you obviously couldn’t sail without them! There are many different sails depending on the type of sailboat and its rig configuration, and we’ll walk through them together in this article.

The different types of sails on a sailboat

We can divide the selection of sails on a sailboat into three categories:

Standard sails

Light-wind sails

Storm sails

Each category serves different purposes depending on the vessel’s rig configuration and the sail’s functionality.

The standard sails

The standard sails usually form a sailboat’s basic sail plan and include :

The Mainsail
The Staysail
The Mizzen sail

These sails are the ones that are used most frequently on sloop, ketch, and cutter-rigged sailboats and are usually set up to be ready to use quickly.

Headsails are often rolled up on a furler, while the main and mizzen sail are stored on the boom or furled into the mast.

The halyards and sheets are kept within easy reach, making these sails the primary choice in most situations. Let’s dive further into each of them.

The mainsail is a triangular sail that flies behind the mast on top of the boom . Although it may not always be the largest sail on the vessel, we commonly refer to it as “the main.”

It is a vital sail, and keeping the sail shape trimmed properly on every point of sail is crucial for the stability and performance of the boat.

A Jib sail is a headsail that does not overlap the mainsail. It is typically between 100% and 115% of the foretriangle but can also be smaller. The foretriangle is the triangular area formed by the mast, deck, and forestay. The Jib is often used with a self-tacking system involving a sheet traveler in front of the mast.

This sail is often seen on newer boats with fractional rigs, which typically have a larger mainsail area than the headsail area. However, the Jib is versatile and also used in other configurations.

People often mix the terms Genoa and Jib. Many refer to any headsail as a Jib, which is incorrect. I personally prefer to use the correct terms to avoid confusion .

A Genoa sail resembles a large Jib but extends past the mast and overlaps the mainsail. Genoas are usually larger than 115% of the foretriangle , with sizes ranging from 120% to 150%. They are often used on vessels with masthead rigs and smaller mainsails but are also common on fractional rigs.

The Staysail is typically found on cutter rigs and is set on the inner forestay or cutter stay. It can be combined with other sails, such as a Jib, Genoa, or Yankee, or on its own in stronger winds.

The Staysail is also useful when sailing downwind, as it can be paired with a headsail and extended to opposite sides of the boat using a pole.

The Yankee sail resembles a Genoa and Jib but has a high-cut clew. This shape allows for improved airflow when used with another headsail. The Yankee is often used on cutter-rigged boats in combination with a staysail and is known for its versatility in different wind conditions.

Mizzen Sail

A mizzen sail is similar to the mainsail, only smaller . It is set on the aft mast of a boat with multiple masts, such as a ketch rig. The mizzen sail is usually used to provide balance and stability to the vessel and provides additional power when sailing downwind.

Another handy usage is to fly the mizzen at anchor to keep the bow up against waves and swell.

The light-wind sails are large, made of thin nylon, and typically shaped like a half-balloon. They are a type of headsails that are great when the winds are too light to fill the standard headsail and are often used when sailing downwind.

The four most commonly used light-wind sails are:

The Spinnaker
The Gennaker
The Code Zero
The Parasailor

They all provide excellent forward propulsion on a sailboat but usually require some extra rigging to be set.

Experienced cruisers love to use light-wind sails in nice weather, but they have a critical weakness to be aware of. These sails easily get overpowered when the wind increases, and I strongly advise being careful and observant of the wind conditions when flying them.

(Yes, I have managed to rip mine on one occasion due to getting overpowered, but that’s a different story…)

Let’s continue and take a closer look at each of the light wind sails.

A Spinnaker sail is a large, lightweight downwind sail used at deep angles between 120 and 180 degrees. It is symmetrical in shape with two clews and is often brightly colored.

The Spinnaker is set by using a pole to extend the sail’s clew to the vessel’s side. Then, a sheet is attached to the other clew and led back to the stern of the boat.

A Gennaker sail combines the characteristics of the Genoa and Spinnaker. It is made of nylon like the Spinnaker but is asymmetrical like a Genoa and rigged slightly differently. The tack is attached to the bow, and the clew has a sheet led aft to the cockpit. The Gennaker can be equipped with a snuffer to make it even easier to set up and take down.

It is popular among cruisers because it is simpler to use than a spinnaker and it doesn’t require a pole. The sail is effective at angles between 90 degrees and almost all the way down to 180 degrees, making it versatile for various light-wind conditions.

A Parasailor is similar to the Spinnaker in many aspects but has some distinct differences. It has a double-layer wing that inflates as the sail is filled with air, creating a batten-like effect pushing the leech out while providing lift to the bow.

The wing also helps to prevent the rolling movements you get with a Spinnaker and the collapsing of the leech that can occur with a Gennaker at deep angles.

This makes the parasailor effective at sailing angles between 70 and 180 degrees dead downwind. Parasailors can be set like a Gennaker when reaching or with a pole like the Spinnaker for running downwind.

A Code Zero sail combines some elements of the Genoa and Gennaker. Unlike the Gennaker, the Code Zero has a different shape, allowing it to be used while sailing upwind.

Another benefit is that it can be used with a furler which makes it easy to roll in and out. However, it can’t replace the Gennaker or Spinnaker entirely, as it is not effective at sailing angles deeper than 120 degrees.

If you see a big yacht with three forestay’s, the forward one probably holds a code zero sail. A bow spirit allows the ability to fly additional light wind sails as well!

Storm Sails

The storm sails consist of a small Mainsail and Jib in heavy-duty materials designed for rough conditions. These sails enable us to maintain speed and stability in the boat in severe weather too strong for the standard sails.

Storm sails are often brightly colored , such as red, orange, or yellow, to make them more visible at sea.

Storm Mainsail

A storm mainsail is used when the reefing setup doesn’t allow the standard mainsail area to be reduced enough to prevent overpowering. The sail can handle rough conditions and is excellent for maintaining stability.

A storm Jib is used when the headsail has been furled to the point where it is no longer effective. It is especially useful for sailboats rigged with a Genoa, as the Genoa gets inefficient when heavily reefed. As the storm Jib is smaller than the standard headsail, it also lowers the center of gravity, making the vessel heel less and become more stable.

Explaining the terms for the parts of a sail

Let us talk some more about sails. The goal is to go sailing, right?

Identifying the different parts of the sails is crucial to understanding which lines go where.

Let’s zoom in on a sail and break down the terms :

The head is the top corner of the sail . Most mainsails have a headboard or plate where the halyard is connected, while headsails use a metal ring. A halyard is a line we use to raise and lower sails with.

The leech is the aft part of a sail , located between the clew and head. We use a combination of the outhaul, main sheet, and traveler to trim and adjust the leech on the mainsail.

The headsail’s leech is trimmed by adjusting sheet tension and angle according to the wind speed and direction. A traveler is a track with a movable car or pulley system for adjusting the position and angle of a sheet, and most sailboats have one main traveler for the mainsail and car tracks along the side decks for the headsail.

The luff of a sail is the front part of the sail between the tack and head. On a mainsail, the luff runs vertically along the mast and along or close to the forestay on a headsail. Headsails are often equipped with luff foam to help maintain their shape when partially reefed on a furler.

Battens are slats or tubes inserted into pockets on the mainsail to help the sail maintain its shape and increase its lifespan . A traditional sail hoisted and lowered on the boom typically has horizontal battens. Vessels with in-mast furling can use vertical battens instead of horizontal ones.

A fully battened Mainsail has the battens run through the entire sail length from the luff to the leech.
A standard battened main sail has the battens along the sail’s leech.

Telltales are small ropes, bands, or flags attached to a sail to give an indication of the airflow around the sail. They help us understand how the wind affects the sail and allow us to fine-tune the trim for optimal performance. Telltales are usually found on the mainsail’s leech and in the front of the headsail’s leech.

The clew of a sail is the lower aft corner and where the outhaul is connected on a mainsail. Headsails have sheets attached to their clew for controlling and trimming the shape and tension.

The tack is the lower, forward corner of a sail. On a traditional Mainsail, the tack is attached to the Gooseneck, a hinge in front of the boom attached to the mast.

With in-mast furling, the tack is connected to the furling mechanism. This mechanism is used to roll the sail into the mast.

The headsails tack is connected to a furler drum on the forestay on most sailboats. Vessels using traditional hank-on headsails connect the tack to a fixed point on the bow.

The foot of the mainsail is the bottom portion of the sail between the clew and the tack. It is trimmed using the outhaul, a line attached to the clew, and used to adjust the tension on the foot of the sail. Some mainsail are configured loose-footed, and others are attach-footed.

The foot of the headsail is trimmed by adjusting the tension and angle of the sheets, which are the lines used to control the headsail’s clew. We use cars, or pulleys, to adjust the angle of the sheets and thus the trim of the headsail.

Traditional and less commonly seen sails

We’ve now looked at the most commonly used sails and walked through the different parts of them. But what about the less common ones? The art of sailing has a rich history, with some unique sail designs that we rarely see today.

Read on if you want to peek into some traditional sails, or skip straight to popular sail and mast configurations here.

Square sails

Square sails are rectangular and usually set across a ship’s mast, mostly seen on traditional square-rigged sailing ships and Viking ships. These sails are efficient for downwind sailing and are hung from horizontal spars called yards. Though not as agile as modern fore-and-aft sails when sailing upwind, they were central to naval exploration for centuries. Today, they’re mainly seen on traditional vessels and tall ships, symbolizing maritime heritage.

If you’ve been to Martinique in the summer, you may also have noticed the round skiff sailboats the local fishermen traditionally used for fishing in the Atlantic Ocean with their distinctive big squared sails. Tour de Martinique des Yoles Rondes is a popular yearly event where the locals race and show off these beautiful old boats with colorful sails!

A gaff sail is a traditional four-sided sail held up by a horizontal spar called the “gaff.” They are used on classic gaff-rigged sailboats and allow for a larger sail area with a shorter mast. Gaff-rigged boats were traditionally popular and usually carried 25% more sail area than the equivalent Bermudan rig, making them fast on a downwind run. The Gaff rig could also carry a topsail between the gaff and the mast.

However, they don’t sail well to windward, and modern designs have shifted towards triangular sails for better upwind performance.

Jib-headed topsail

The Jib-headed topsail is a small triangular sail used on gaff rigs and is set between the gaff and the top of the mast.

A lug sail is an angled, four-sided sail that attaches at a point on its top side, making it hang tilted. The sail is simple to use and often found on smaller or older boats. There are different types, like standing, dipping, and balance lugs, each hanging differently around the mast.

The lug sail evolved from the square sail to improve how close the vessels could sail into the wind. Because of their upwind performance, fishermen used them widely in Europe from the seventeenth through the nineteenth centuries.

Sprit sails

The spritsail, with its unique four-sided design, stands out thanks to a diagonal support called the “sprit.” It was traditionally popular in Thames sailing barges due to its ability to accommodate high-deck cargo. These days, it’s primarily found in smaller boats like the Optimist dinghy in a variant called “leg of mutton spritsail.”

The spritsail was also used in traditional wooden boats like the fearing version of the Oselvar wooden boat traditionally used in western Norway.

It is also commonly used by the indigenous Guna Yala tribes in Panama in their dugout Ulu’s up to this day. We saw plenty of them when we cruised along the coast, and some of them approached us to sell us their delicious catch of the day!

Lateen sails

A lateen sail is a triangular sail set on a long spar angled on the mast. It was originally popular in the Mediterranean and on Arab shows, and its design enhanced maneuverability and played a crucial role in historic sea exploration.

The lateen sail was used on lateen rigs, the predecessor to the Bermuda rig – one of today’s most commonly used rigs!

Which brings us to the following topic:

Popular sail and mast configurations

There are many different rigs and sail configurations between sailing vessels. From the old-school square rigs to schooners, gaff rigs, and more. However, this article will focus on the three most popular rigs seen on modern sailboats:

The Bermuda Sloop Rig
The Cutter Rig
The Ketch Rig

The three rigs have similarities and differences between their sail and mast configurations. We’ll walk through each of them to understand how they utilize their different types of sail.

If you want to learn more about other rigs, take a look here .

Bermuda Sloop Rig

The Bermuda sloop rig is the most common rig on modern vessels. It is characterized by a single mast, a triangular mainsail, and a headsail. This rig is named after the Bermuda Islands, where it was developed in the 17th century.

Some of the key features of the Bermuda sloop rig:

The mast is typically tall and raked, which allows for a large sail area and excellent stabilit y.
The mainsail is attached to the mast and boom. It is usually combined with a single headsail at the front of the boat, making it powerful and easy to sail.
The Sloop is usually equipped with a masthead or fractional rig and flies a Jib or Genoa as its primary headsail.

The Bermuda Sloop rig is known for its simplicity, is often used for racing and cruising, and is popular among sailors worldwide.

The cutter rig is very similar to the sloop rig. The significant difference is that it has a single mast and two headsails – a Staysail and a Yankee. The cutter rig is known for its versatility due to the multiple options in sail plans and the double headsail setup.

Some key aspects that separate the Cutter from the Sloop:

The rig is often more robust than its Sloop sister because of the additional cutter stay and running backstays.
The mast is located closer to the center of the boat.
The Cutter has a staysail on the inner forestay and a Yankee sail on the outer. The sails can be used in combination with each other or independently.
Tacking the headsail between the forestay and cutter stay is more involved than on a sloop.
The Cutter rig has two similar variations: the Slutter rig and the Solent rig.

Like the Sloop, the Cutter rig is relatively easy to operate. Still, the additional headsail and rigging make it costlier to maintain. It is also less suitable for racing than the Sloop, but the added versatility helps in different weather conditions and makes it an excellent choice for cruisers.

The ketch rig is also similar to the Sloop but has an additional mizzen mast placed further aft of the main mast. Another mast gives it the advantage of even higher versatility in sail plans. The ketch typically uses three sails. The mizzen sail, a mainsail, and a headsail. The mizzen mast also allows it to fly a second light-wind sail.

Here are a few more distinctions of the ketch rig:

The ketch typically carries a smaller mainsail than a similarly sized sloop and a smaller mizzen sail.
A small mizzen and a medium mainsail are easier to handle than one large mainsail.
The additional mizzen sail makes the vessel easy to balance and gives extra stability downwind.
The ketch usually doesn’t point as close to the wind as the Sloop and Cutter.

The headsail setup on a ketch is generally the same as for the Sloop. But the ketch can also be rigged as a cutter ketch, which gives it the benefits of the cutter rig! The tradeoff with a cutter-rigged ketch is the higher complexity and additional rigging, hardware, and sails required.

Final words

Well done, you now have a good grasp of the most common sails and their strengths. We have discussed a few rigs and how they utilize different kinds of sails in various sail plans. Remember that more sail types, other rigs, and even more variations are available. It is a complex topic, but this guide covers the basics and gives you a great starting point.

If you still have questions, look below at the FAQ, or leave me a comment. I’m more than happy to help you out!

A sailboat is only as good as its sails, and sails need wind to work. The next logical step is learning how the wind works when we sail and practicing some wind awareness! Head to the following guide to continue your research: Learn The Difference Between True And Apparent Wind Speed.

FAQ: The Different Types of Sails On A Sailboat

What is the foretriangle on a sailboat.

The foretriangle on a sailboat refers to the triangular area formed between the mast, forestay, and deck. If you want to order a new headsail, for example, you’ll have to measure and supply the sailmaker with these details.

What is the difference between a loose-footed and attached-footed mainsail?

A loose-footed mainsail is attached to the boom only at its corners, leaving the rest of the sail’s bottom edge free. An attached-footed mainsail, on the other hand, is secured to the boom along its entire length. The main difference lies in how the bottom of the sail connects to the boom, with the loose-footed design offering more adjustability in the sail shape.

What is a high-cut clew on a sail?

A high-cut clew refers to the design of a foresail, such as a jib or genoa, where the back lower corner (the clew) is raised or “cut” higher above the deck compared to standard designs. This design allows for better visibility beneath the sail and makes it easier to sail over waves without the sail touching the water, which is especially beneficial for offshore or blue-water cruising. Very high-cut clews are commonly seen on yankee sails on cutter-rigged sailboats.

What is luff foam on a sail?

Luff foam is a padded strip sewn into the forward edge of roller furling sails. It ensures the sail is appropriately shaped when partially rolled up, especially in strong winds. This foam not only helps with sail performance but also protects the sail when it’s furled.

What are the most common sails?

The sloop rig sailboat is the most common and usually features a mainsail, a headsail, and an additional light-wind sail, such as a spinnaker or Gennaker.

What are the different types of sails?

There are several different types of sails, and we can divide the most common into three categories:

The standard sails:

Mizzen sail

The light-wind sails

The storm sails:

Storm mainsail
Storm jib

What is a spinnaker sail?

A Spinnaker sail is a large, lightweight downwind sail used at deep angles between 120 and 180 degrees.

What is a Jib sail?

A Jib sail is a headsail that does not overlap the mainsail and is set on the forestay. The Jib can also be set up with a self-tacking system, making it very effective when sailing into the wind.

Is Genoa sail the same as a jib?

People often mix the terms Genoa and Jib. The Genoa is different from a Jib sail as it is larger and overlaps the mainsail, whereas the Jib is smaller and does not overlap the mainsail.

What is a Genoa sail?

A Genoa is a headsail larger than the Jib extending past the mast and overlapping the mainsail. The advantage over the Jib is the larger sail area, making it more effective when sailing off the wind.

How many types of sail plans are there?

Sail plans refer to the configuration and arrangement of sails on a boat or ship. While there are countless customizations and variations, the three most common sail plans are:

Sloop: Characterized by a single mast, a triangular mainsail, and a headsail.

Cutter: Similar to a sloop but has a single mast and carries two or more headsails.

Ketch: Features two masts, with the aft mast (called the mizzen) shorter than the main mast.

What is a Mainsail?

The mainsail is a triangular sail that flies behind the mast on top of the boom.

What is a Gennaker?

A gennaker is basically an asymmetrical spinnaker. A hybrid sail that combines the characteristics of a Genoa and a Spinnaker, designed for sailing off the wind and often used in light to moderate wind conditions.

What is a Storm Jib?

A storm jib is a small, heavy-duty sail used in strong winds or stormy conditions. It is commonly used when the headsail has been furled to the point where it is no longer effective.

What factors determine the type of sail to be used?

The type of sail to be used depends on various factors such as wind conditions, points of sail, sailboat size , and sailing experience. It’s smart to choose the appropriate sail for optimal performance. A Jib, for example, will be more effective than a Genoa while sailing to windward, and vice versa.

How do sails affect the performance of a sailboat?

Sails are the engine of a sailboat. Their design, size, and trim influence the boat’s speed, direction, and stability. Properly adjusted sails capture wind efficiently, allowing the boat to move faster and in the desired direction.

The balance and condition of the sails also impact comfort and safety, with well-maintained sails ensuring optimal performance. The sails are essential in determining how a sailboat performs in various wind conditions.

How Sails Work: Understanding the Basics

Table of Contents

Last Updated on September 1, 2023 by Boatsetter Team

Sailing is all about physics and geometry but don’t worry, it’s not too hard to learn. Once the theory is down, it’s all a matter of practice. Let’s look at what sails are and how they work.

Book a sailboat rental & set out on your next expedition

Aerodynamics, hydrodynamics & modern sails

Sails work like airplane wings, except they’re vertical rather than horizontal. As the wind hits the front of a curved sail, it splits, passing on both the downwind (leeward) side and upwind (windward) side.

The leeward wind travels farther due to the curvature of the sail and creates a low-pressure area while the windward wind travels a shorter distance and reaches the aft end faster – together, they create aerodynamic lift that “pulls” the boat forward .

The keel or centerboard in the water below the hull prevents the boat from being pushed sideways. With the lift of the sails and the lateral push or hydrodynamics of the keel, the boat is propelled forward. Where the wind concentrates force in the sails is called the center of effort, while the keel below is called the center of lateral resistance.

Most modern sailboats have a forward (or headsail) and a mainsail. The headsail may be called a genoa, jib, or staysail (different sizes) and is attached at the top of the mast and leads down at an angle to the bow . It’s controlled by lines called sheets. The mainsail is supported by the mast and is attached at the bottom to a lateral spar called the boom.

Parts of a sail

Sails come in various shapes, but for our purposes, we will focus on modern, triangular sails. The top of the sail is called the head , and the bottom is the foot. The forward end of the foot is the tack, and the aft end is the clew. The forward edge of the sail is the luff, and the aft end is the leach.

Telltales or short strands of yarn are often attached near the leading edge of a sail to help with sail trim. The shape of the sail is ideal when the strands on both sides are streaming back at the same level, which indicates that wind is moving evenly along both sides of the sail.

Points of sail

A boat cannot sail directly into the wind– instead, it sails at an angle to the true breeze. Close hauled is roughly 45 degrees off the wind, close reach is 60 degrees, beam reach is at 90 degrees, and a broad reach is approximately 150 degrees off the wind.

When moving directly or dead downwind, a boat is said to be running, and when the bow is pointed into the wind, that’s called being in irons. A boat cannot sail in irons and can be hard to control when running. When sails begin to luff at the leading edge, the boat is trying to sail too close to the wind and will stall.

Tacking and jibing (gybing)

A boat changes direction by either tacking or jibing. Sailing upwind, a boat tacks when the bow passes through the eye of the wind until the boat is sailing on the opposite side or “tack” creating a zig-zag course. When sailing downwind, the boat jibes when passing the stern through the wind.

Turning upwind is called heading up and turning away, or downwind is falling off. When the wind passes over the starboard rail first, you’re on a starboard tack and vice versa.

Pro Tip: You can learn how to sail without owning a sailboat. Find a sailboat rental near you , then book! You can save that boat listing and book again to continue practicing.

Sail shape & angle

Boats sail in true wind (the wind that is actually blowing at a given speed and angle) by they’re actually responding to the apparent wind (the angle and speed of the breeze that is felt once the boat is moving). The wind always changes speed and angle, so sails must be adjusted or trimmed in response to the boat to maintain optimal speed.

When sailing upwind, the sails are sheeted in (made flatter by pulling in the sheet lines) to create better foils and greater lift or pull. When sailing downwind, sails are usually loosened or let out to create a “belly” and adjusted to be as perpendicular to the angle of the wind as possible.

Sheeting in (bringing the sails closer to the centerline) enables the boat to point higher (sail closer to the true wind) while easing out (loosening the aft end of the sail) creates more power when the wind is aft like around the beam or broad reach.

A boat is more likely to heel when sheeted in and sailing upwind. Excessive healing doesn’t mean the boat is traveling faster. In fact, it may just be getting overpowered and becoming less efficient than if the sails were trimmed properly.

In high winds, shorten or reef sails so the boat doesn’t become overpowered and potentially dangerous. Reefing is done at the tack and clue or the forward and aft parts of the foot of the sail. There may be 1-3 pre-rigged reefing points controlled by reefing lines, so the sails can be made as small as necessary to keep the boat from heeling too far.

Easy to learn

Trimming sails takes time to master; let sails out until they luff or flap, and then sheet in until you feel the boat pick up speed. Smaller boats react quickly to each adjustment and are better for new sailors to learn on than large boats that take a minute to speed up or slow down. Once you’ve mastered the theory, you may spend years perfecting your sailing skills.

The Different Types Of Sails And When To Use Them – Complete Guide

Sail forms an integral part of a sailboat. When you sail on the open water and observe other boats (in various sizes), you’d have noticed how each boat type has a specific model of sail. If you’re a beginner in boating, you must know that there are a ton of different sails and they each have their own purpose.

As a general setup, sailboats will use three common sails, including headsail, mainsail, and specialty sail. Due to the varying wind conditions and the model of the sailboat, there are many types of sails including jib, genoa, trysail, storm jib, code zero, gennaker, and spinnaker.

While that sounds like too many models of sails, you can easily differentiate between them and choose the ideal model based on your purpose. This article guides you on this aspect. Let’s begin!

Different Types of Sails & When To Use Them

1. mainsail.

Mainsail is by far the most widely spotted sail model, and it’s usually fixed to the boom and fitted behind the mast. This offers the highest mileage to your sailboat, thereby maximizing speed and performance.

You can use a mainsail if:

You’re concerned about the performance
You need to go faster and utilize all wind power
You need to steer your boat irrespective of the wind’s status
You’ve a large boat and can offer adequate space to this sail.

This mainsail displays a wide surface area to make the most out of the available wind condition. As a result, you can steer your boat quite easily. However, the downside is its size. It is very large and hard to store if you need to take it down for some reason.

Check out my other article all about maintaing sails!

2. Headsail

Similar to a mainsail, it’s very easy to spot a head sail. Just look at the bow of the boat and see if there is a sail. If you see one then yes that’s a headsail. Also called a jib or genoa, a headsail is smaller in size compared to a mainsail and attaches in front of the mast to the forestay. The Foresail will not have a boom for the clew of the sail to attach to. The clew will be attached to the foresails sheet. It can be used without the mainsail in certain conditions but for the most part the two sails are used together. The foresail is always forward of the main.

The headsail comes in many different forms such as a jib, genoa, spinnaker or storm jib. The most common headsail is a jib or genoa.

You can use a headsail if:

Your sailboat is set up for it.
You don’t want to use the mainsail at this time.
Your mainsail is not usable.

The biggest advantage of a headsail is the option to protect yourself even if the wind turns unpredictable or wild. This all depends on the type of headsail you are using.

So, what are the different types of headsails? Let’s take a look!

As more boaters chose to use a headsail for their boats, the jib was introduced as one of its forms. The Jib is a form of headsail that is attached to a shackle present on the deck’s front region.

The Jib is a sail that does not go past the mast when it is raised and in use. If it goes past the mast then you probably have a genoa.

You can use a jib if:

You are out for a normal day of sailing in moderate wind speeds
You have a roller furling. Which is a sail that wraps up around itself.

Some weather conditions can make maneuvering harder or tighter than usual. As a result, it’s essential to use a jib in such cases. It functions well with boats containing a roller furling as the jib handles different positions and tackles the movement of the boat at ease.

2.2 Genoa

Just when you’ve got acquainted with the jib, genoa comes into the picture as a larger version of the jib. If you’re boating along a coastal region, the genoa sail is the one widely used and is attached to the front area of the deck as well.

Here’s a quick trick to find out if a boat has a genoa sail. This genoa is usually larger than a Jib. This means that the genoa effortlessly overlaps and extends itself beyond the mast, thereby covering the mainsail as well.

You should use a genoa sail if:

You’re planning to sail in minimum wind conditions. Less wind means you need more sail.
You find the wind to originate from the rear area.
You own a large boat. Remember that genoa can partially or completely cover the mainsail too. Larger sails for larger boats!

While it’s great for sailing in regular conditions, there are downsides associated with it. A genoa can put you in a dangerous situation if you are sailing in high wind conditions and don’t have the ability to furl in the sail. Furling in the sail will reduce the area of the sail and catch less wind.

Genoas do come in many sizes as well such as 110% or 120%.

The next section of the sail list are ones that aren’t necessary but can be helpful in certain situations. Let’s look at specialty sails!

3. Specialty Sail

While headsails and mainsails are quite commonly used, there are also specialty sails in the market to address specific requirements. Some of the widely seen specialty sails are spinnakers, storm jibs, and code zeros.

3.1 Spinnakers

Spinnaker is a sail dedicated to downwind and is quite large. Think of a beautifully covered parachute.

It’s easy to spot spinnakers as they resemble kites or parachutes. However, it crosses the bow of the boat and isn’t attached to the forestay.

Unlike the genoa sail that covers the mast, a spinnaker fails to do so. The advantage of a spinnaker is the surface area. When the wind is light, the spinnaker can catch a lot more wind giving you more speed. The Spinnaker is usually fixed to three points – pole, halyard, and sheet.

You should use a spinnaker if:

You have minimal wind on a run.
You are trying to harness as much wind power as you can.

While it has a wide surface area, the downside is its inability to steer the boat during strong wind conditions. It can even put the passengers at risk when the wind is at high speeds.

Make sure you have experience before trying out the spinnaker.

3.2 Storm Jibs

Storm jib is another type of specialty sail meant exclusively for rough weather. It’s a tiny, triangular structure that helps during offshore racing or cruising. Just think of it as a smaller jib.

You should use a storm jib if:

You’re going to sail in heavy weather conditions.
You anticipate high wind speeds.
You’re going to be in an offshore race and they are an approved sail type.

Note: In the case of an offshore racing requirement, it’s critical to take prior permission from the regulatory authority for using a storm jib.

3.3 Code Zeros

Code zero is another updated version of a spinnaker that’s meant to be a combination of genoa and gennaker sails. It resembles the look of a genoa but is a lot bigger.

You should use a code zero if:

You’re looking for an overlapping flying headsail.
You’re sailing only in light air conditions.
You’re looking for an alternative to a Genoa.

Having said that, a code zero or a screecher does the job of a genoa with better efficiencies.

3.4 Trysail

Trysail is another type of specialty sail that’s tiny, triangular, and can be fixed right above a gooseneck on the sailboat.

The Trysail is less known in the market as most boaters go ahead with common mainsails and headsails. It’s essential to acknowledge trysail as a front-and-aft mainsail model. It offers excellent performance and contains a permanent pennant in it.

You should use a trysail if:

You’re sailing in heavy weather conditions.
You’re looking for a storm replacement.
You are experienced with using them.

The quadrilateral sail in a trysail is usually turned and bent to a mast, and this helps in heading the vessel during windy conditions.

3.5 Gennakers

If you’ve been able to spot genoa and spinnaker in the past, identifying a gennaker is incredibly easy. A gennaker is a hybrid sail form that is small, slow, and requires no pole attached to the mast.

You should use a gennaker if:

You’re looking for a smaller version of a spinnaker.
You’ve no space to fix a pole to the mast.
You require the sail to be easily manageable.
You’re sailing in a region requiring minimum downwind levels.

Choosing a hybrid sail has a lot of benefits as it combines the usefulness of 2 sail models. However, being aware of their cons is critical to planning a safe sail.

As you begin using these sails, you can also look for better customizations. There are drifters, wind seekers, and other jib types that are meant to handle different wind conditions.

How Many Sails On A Sailboat ?

In general, a sailboat contains two sails. Two sails is the typical setup for the best performance of the boat during different wind conditions. It’s essential to pick your two sails based on your sailing plan.

Why Are There Two Sails On A Sailboat?

A sailboat uses two sails because the wind left over by the first sail is easily caught by the second sail. This helps in steering the sailboat to a better extent and gives the sailboat more power.

Final Thoughts

Sails are one of the major assets of a sailboat. From managing wind to maximizing the performance and longevity of a sailboat, the type of sails you use, plays a huge role. From the various sail types listed in this article, you can choose the best model that fits your sailing routine. Just make sure to remember to check and make sure they are the correct size for your vessel.

Make sure to plan ahead and have the right sails for your sailing weekend. Cheers!

The required sail dimensions for calculating the area of any triangular sails are usually its height and the length of its foot. But that only works for mainsails and mizzens with no roach, and jibs with a 90 degree angle at the clew - and what about high-cut headsails, spinakers and cruising chutes? Read on...

Foresail and mainsail dimensions are universally referenced with the letters 'J', 'I', 'E' and 'P' approximating to the length of the foredeck, height of the mast, length of the boom and the height of the main sail - but more accurately defined further down this page.

Yacht designers need these sail dimensions to calculate thought provoking stuff such as the sail-area/displacement ratios of their creations, and sailmakers need them before they put scissors to sailcloth.

If our sailboat's sails were perfectly triangular then, as every schoolboy knows, their area would be 'half the height, times the base' - but with the possible exception of a mainsail with a straight luff, generally they're not. Here's how it works...

Main and Mizzen Sail Dimensions

These are almost right-angled triangles except for the curvature of the leach (the 'roach') which increases the sail area.

It's usually calculated as:~

Area = (luff x foot)/1.8, or

Area = ( P x E )/1.8, where:~

'P' is the distance along the aft face of the mast from the top of the boom to the highest point that the mainsail can be hoisted, and
'E' is the distance along the boom from the aft face of the mast to the outermost point on the boom to which the main can be pulled.

For the mizzen sails on ketches and yawls , 'P' and 'E' relate to the mizzen mast and boom.

For more heavily roached sails, the increased area can be accounted for by reducing the denominator in the formula to 1.6.

Clearly calculating sail areas isn't going to be an exact science...

Jibs, Genoas and Staysail Dimensions

For a working jib that fills the fore triangle - but no more - and with a foot that's parallel to the deck, then you've got a 'proper' right-angled triangular sail, whose area is:~

Area = (luff x foot)/2, or

Area = ( I x J )/2, where:~

'I' is the distance down the front of mast from the genoa halyard to the level of the main deck, and
'J' is the distance along the deck from the headstay pin to the front of the mast.

Genoas, by definition, have a clew which extends past the mast and are described by the amount by which they do so. For instance a 135% genoa has a foot 35% longer than 'J' and a 155% genoa 55% longer. Areas are calculated as follows:~

Area (135% genoa) = (1.44 x I x J )/2, and

Area (155% genoa) = (1.65 x I x J )/2

High-cut Headsails

The 'luff perpendicular' is needed for measuring the area of a high-cut jib

But these formulae don't work for a high-cut jib with a raised clew - unless you imagine the sail turned on its side such that the luff is the base and the luff perpendicular is the height.

It's still a simple calculation though, once you know the length of the luff perpendicular ( LP ), the sail area is:~

Area = (luff x luff perpendicular)/2, or

Area = ( L x LP )/2, where:~

'L' is the distance along the forestay from the headstay pin to the front of the mast, and
'LP' is the shortest distance between the clew and the luff of the genoa.

Spinnaker Sail Dimensions

Much like calculating foresail areas, but with different multipliers for conventional spinnakers and asymmetric spinnakers...

Conventional Spinnakers

Area = (0.9 x luff x foot), or

Area = (0.9 x I x J ), where:~

'I' is the distance from the highest spinnaker halyard to the deck, and
'J' is the length of the spinnaker pole.

Asymmetric Spinnakers

Area = (0.8 x luff x foot), or

Area = (0.8 x I x J ), where:~

'I' is the distance from the highest spinnaker halyard to the deck, and
'J' is the distance from the front face of the mast to the attachment block for the tackline.

Guide to Understanding Sail Rig Types (with Pictures)

There are a lot of different sail rig types and it can be difficult to remember what's what. So I've come up with a system. Let me explain it in this article.

What are the different types of sail rig? The sail rig is determined by the number of masts and the layout and shape of sails. Most modern ships are fore-and-aft rigged, while old ships are square-rigged. Rigs with one mast are sloops and cutters. Ketches, yawls, brigs, and schooners have two masts. Barques have three masts. Rigs can contain up to seven masts.

'Yeah, that's a gaff brig, and that a Bermuda cutter' - If you don't know what this means (neither did I) and want to know what to call a two-masted ship with a square-rigged mainsail, this article is definitely for you.

The Ultimate Guide to Sail Types and Rigs (with Pictures)

First of all, what is a sail rig? A sail rig is the way in which the sails are attached to the mast(s). In other words, it's the setup or configuration of the sailboat. The rig consists of the sail and mast hardware. The sail rig and sail type are both part of the sail plan. We usually use the sail rig type to refer to the type of boat.

Let's start by taking a look at the most commonly used modern sail rigs. Don't worry if you don't exactly understand what's going on. At the end of this article, you'll understand everything about rig types.

Diagram of most common rig types (Bermuda sloop, gaff cutter, gaff ketch, gaf schooner, full rigged ship)

The sail rig and sail plan are often used interchangeably. When we talk of the sail rig we usually mean the sail plan . Although they are not quite the same. A sail plan is the set of drawings by the naval architect that shows the different combinations of sails and how they are set up for different weather conditions. For example a light air sail plan, storm sail plan, and the working sail plan (which is used most of the time).

So let's take a look at the three things that make up the sail plan.

The 3 things that make up the sail plan

I want to do a quick recap of my previous article. A sail plan is made up of:

Mast configuration - refers to the number of masts and where they are placed
Sail type - refers to the sail shape and functionality
Rig type - refers to the way these sails are set up on your boat

I'll explore the most common rig types in detail later in this post. I've also added pictures to learn to recognize them more easily. ( Click here to skip to the section with pictures ).

How to recognize the sail plan?

So how do you know what kind of boat you're dealing with? If you want to determine what the rig type of a boat is, you need to look at these three things:

Check the number of masts, and how they are set up.
You look at the type of sails used (the shape of the sails, how many there are, and what functionality they have).
And you have to determine the rig type, which means the way the sails are set up.

Below I'll explain each of these factors in more detail.

The most common rig types on sailboats

To give you an idea of the most-used sail rigs, I'll quickly summarize some sail plans below and mention the three things that make up their sail plan.

Bermuda sloop - one mast, one mainsail, one headsail, fore-and-aft rigged
Gaff cutter - one mast, one mainsail, two staysails, fore-and-aft rigged
Gaff schooner - two-masted (foremast), two mainsails, staysails, fore-and-aft rigged
Gaff ketch - two-masted (mizzen), two mainsails, staysails, fore-and-aft rigged
Full-rigged ship or tall ship - three or more masts, mainsail on each mast, staysails, square-rigged

The first word is the shape and rigging of the mainsail. So this is the way the sail is attached to the mast. I'll go into this later on. The second word refers to the mast setup and amount of sails used.

Most sailboats are Bermuda sloops. Gaff-rigged sails are mostly found on older, classic boats. Square-rigged sails are generally not used anymore.

But first I want to discuss the three factors that make up the sail plan in more detail.

Ways to rig sails

There are basically two ways to rig sails:

From side to side, called Square-rigged sails - the classic pirate sails
From front to back, called Fore-and-aft rigged sails - the modern sail rig

Almost all boats are fore-and-aft rigged nowadays.

Square sails are good for running downwind, but they're pretty useless when you're on an upwind tack. These sails were used on Viking longships, for example. Their boats were quicker downwind than the boats with fore-and-aft rigged sails, but they didn't handle as well.

The Arabs first used fore-and-aft rigged sails, making them quicker in difficult wind conditions.

Quick recap from part 1: the reason most boats are fore-and-aft rigged today is the increased maneuverability of this configuration. A square-rigged ship is only good for downwind runs, but a fore-and-aft rigged ship can sail close to the wind, using the lift to move forward.

The way the sails are attached to the mast determines the shape of the sail. The square-rigged sails are always attached the same way to the mast. The fore-and-aft rig, however, has a lot of variations.

The three main sail rigs are:

Bermuda rig - most used - has a three-sided (triangular) mainsail
Gaff rig - has a four-sided mainsail, the head of the mainsail is guided by a gaff
Lateen rig - has a three-sided (triangular) mainsail on a long yard

The Bermuda is the most used, the gaff is a bit old-fashioned, and the lateen rig is outdated (about a thousand years). Lateen rigs were used by the Moors. The Bermuda rig is actually based on the Lateen rig (the Dutch got inspired by the Moors).

Diagram of lateen, gaff, and bermuda rig

Other rig types that are not very common anymore are:

Junk rig - has horizontal battens to control the sail
Settee rig - Lateen with the front corner cut off
Crabclaw rig

Mast configuration

Okay, we know the shape of the mainsail. Now it's time to take a look at the mast configuration. The first thing is the number of masts:

one-masted boats
two-masted boats
three-masted boats
four masts or up
full or ship-rigged boats - also called 'ships' or 'tall ships'

I've briefly mentioned the one and two mast configurations in part 1 of this article. In this part, I'll also go over the three-masted configurations, and the tall ships as well.

A boat with one mast has a straightforward configuration because there's just one mast. You can choose to carry more sails or less, but that's about it.

A boat with two masts or more gets interesting. When you add a mast, it means you have to decide where to put the extra mast: in front, or in back of the mainmast. You can also choose whether or not the extra mast will carry an extra mainsail. The placement and size of the extra mast are important in determining what kind of boat we're dealing with. So you start by locating the largest mast, which is always the mainmast.

From front to back: the first mast is called the foremast. The middle mast is called the mainmast. And the rear mast is called the mizzenmast.

Diagram of different mast names (foremast, mainmast, mizzenmast)

What is the mizzenmast? The mizzenmast is the aft-most (rear) mast on a sailboat with three or more masts or the mast behind the mainmast on a boat with two masts. The mizzenmast carries the mizzen sail. On a two-masted boat, the mizzenmast is always (slightly) smaller than the mainmast. What is the purpose of the mizzen sail? The mizzen sail provides more sail area and flexibility in sail plan. It can be used as a big wind rudder, helping the sailor to have more control over the stern of the ship. It pushes the stern away from the wind and forces the bow in the opposite way. This may help to bring the bow into the wind when at anchor.

I always look at the number of masts first, because this is the easiest to spot. So to make this stuff more easy to understand, I've divided up the rig types based on the number of masts below.

Why would you want more masts and sail anyways?

Good question. The biggest advantage of two masts compared to one (let's say a ketch compared to a sloop), is that it allows you to use multiple smaller sails to get the same sail area. It also allows for shorter masts.

This means you reduce the stress on the rigging and the masts, which makes the ketch rig safer and less prone to wear and tear. It also doesn't capsize as quickly. So there are a couple of real advantages of a ketch rig over a sloop rig.

In the case of one mast, we look at the number of sails it carries.

Boats with one mast can have either one sail, two sails, or three or more sails.

Most single-masted boats are sloops, which means one mast with two sails (mainsail + headsail). The extra sail increases maneuverability. The mainsail gives you control over the stern, while the headsail gives you control over the bow.

Sailor tip: you steer a boat using its sails, not using its rudder.

The one-masted rigs are:

Cat - one mast, one sail
Sloop - one mast, two sails
Cutter - one mast, three or more sails

Diagram of one-masted rigs (bermuda cat, bermuda sloop, gaff cutter)

The cat is the simplest sail plan and has one mast with one sail. It's easy to handle alone, so it's very popular as a fishing boat. Most (very) small sailboats are catboats, like the Sunfish, and many Laser varieties. But it has a limited sail area and doesn't give you the control and options you have with more sails.

The most common sail plan is the sloop. It has one mast and two sails: the main and headsail. Most sloops have a Bermuda mainsail. It's one of the best racing rigs because it's able to sail very close to the wind (also called 'weatherly'). It's one of the fastest rig types for upwind sailing.

It's a simple sail plan that allows for high performance, and you can sail it short-handed. That's why most sailboats you see today are (Bermuda) sloops.

This rig is also called the Marconi rig, and it was developed by a Dutch Bermudian (or a Bermudian Dutchman) - someone from Holland who lived on Bermuda.

A cutter has three or more sails. Usually, the sail plan looks a lot like the sloop, but it has three headsails instead of one. Naval cutters can carry up to 6 sails.

Cutters have larger sail area, so they are better in light air. The partition of the sail area into more smaller sails give you more control in heavier winds as well. Cutters are considered better for bluewater sailing than sloops (although sloops will do fine also). But the additional sails just give you a bit more to play with.

Two-masted boats can have an extra mast in front or behind the mainmast. If the extra mast is behind (aft of) the mainmast, it's called a mizzenmast . If it's in front of the mainmast, it's called a foremast .

If you look at a boat with two masts and it has a foremast, it's most likely either a schooner or a brig. It's easy to recognize a foremast: the foremast is smaller than the aft mast.

If the aft mast is smaller than the front mast, it is a sail plan with a mizzenmast. That means the extra mast has been placed at the back of the boat. In this case, the front mast isn't the foremast, but the mainmast. Boats with two masts that have a mizzenmast are most likely a yawl or ketch.

The two-masted rigs are:

Lugger - two masts (mizzen), with lugsail (a cross between gaff rig and lateen rig) on both masts
Yawl - two masts (mizzen), fore-and-aft rigged on both masts. Main mast is much taller than mizzen. Mizzen without a mainsail.
Ketch - two masts (mizzen), fore-and-aft rigged on both masts. Main mast with only slightly smaller mizzen. Mizzen has mainsail.
Schooner - two masts (foremast), generally gaff rig on both masts. Main mast with only slightly smaller foremast. Sometimes build with three masts, up to seven in the age of sail.
Bilander - two masts (foremast). Has a lateen-rigged mainsail and square-rigged sails on the foremast and topsails.
Brig - two masts (foremast), partially square-rigged. The main mast carries small lateen-rigged sail.

Diagram of two-masted rigs (gaff yawl, gaff ketch, gaff schooner, and brig)

The yawl has two masts that are fore-and-aft rigged and a mizzenmast. The mizzenmast is much shorter than the mainmast, and it doesn't carry a mainsail. The mizzenmast is located aft of the rudder and is mainly used to increase helm balance.

A ketch has two masts that are fore-and-aft rigged. The extra mast is a mizzenmast. It's nearly as tall as the mainmast and carries a mainsail. Usually, the mainsails of the ketch are gaff-rigged, but there are Bermuda-rigged ketches too. The mizzenmast is located in front of the rudder instead of aft, as on the yawl.

The function of the ketch's mizzen sail is different from that of the yawl. It's actually used to drive the boat forward, and the mizzen sail, together with the headsail, are sufficient to sail the ketch. The mizzen sail on a yawl can't really drive the boat forward.

Schooners have two masts that are fore-and-aft rigged. The extra mast is a foremast which is generally smaller than the mainmast, but it does carry a mainsail. Schooners are also built with a lot more masts, up to seven (not anymore). The schooner's mainsails are generally gaff-rigged.

The schooner is easy to sail but not very fast. It handles easier than a sloop, except for upwind, and it's only because of better technology that sloops are now more popular than the schooner.

The brig has two masts. The foremast is always square-rigged. The mainmast can be square-rigged or is partially square-rigged. Some brigs carry a lateen mainsail on the mainmast, with square-rigged topsails.

Some variations on the brig are:

Brigantine - two masts (foremast), partially square-rigged. Mainmast carries no square-rigged mainsail.

Hermaphrodite brig - also called half brig or schooner brig. Has two masts (foremast), partially square-rigged. Mainmast carries a gaff rig mainsail and topsail, making it half schooner.

Three-masted boats are mostly barques or schooners. Sometimes sail plans with two masts are used with more masts.

The three-masted rigs are:

Barque - three masts, fore, and mainmast are square-rigged, the mizzenmast is usually gaff-rigged. All masts carry mainsail.
Barquentine - three masts, foremast is square-rigged, the main and mizzenmast are fore-and-aft rigged. Also called the schooner barque.
Polacca - three masts, foremast is square-rigged, the main and mizzenmast are lateen-rigged.
Xebec - three masts, all masts are lateen-rigged.

Diagram of three-masted rigs (barque, full rigged ship)

A barque has three or four masts. The fore and mainmast are square-rigged, and the mizzen fore-and-aft, usually gaff-rigged. Carries a mainsail on each mast, but the mainsail shape differs per mast (square or gaff). Barques were built with up to five masts. Four-masted barques were quite common.

Barques were a good alternative to full-rigged ships because they require a lot fewer sailors. But they were also slower. Very popular rig for ocean crossings, so a great rig for merchants who travel long distances and don't want 30 - 50 sailors to run their ship.

Barquentine

The barquentine usually has three masts. The foremast is square-rigged and the main and mizzenmast fore-and-aft. The rear masts are usually gaff-rigged.

Faster than a barque or a schooner, but the performance is worse than both.

The polacca or polacre rig has three masts with a square-rigged foremast. The main and mizzenmast are lateen-rigged. Beautiful boat to see. Polacca literally means 'Polish' (it's Italian). It was a popular rig type in the Mediterranean in the 17th century. It looks like the xebec, which has three lateen-rigged masts.

Fun fact: polaccas were used by a Dutch sailor-turned-Turkish-pirate (called Murat Reis).

The xebec is a Mediterranean trading ship with three masts. All masts are lateen-rigged. I couldn't find any surviving xebecs, only models and paintings. So I guess this rig is outdated a long time.

A boat with three or more masts that all carry square-rigged sails is called a ship, a tall ship, or a full-rigged ship. So it's at this point that we start calling boats 'ships'. It has nothing to do with size but with the type of rigging.

More sails mean less stress on all of them. These ships use a lot of sails to distribute the forces, which reduces the stress on the rigging and the masts. Square sails mean double the sail area in comparison to triangular sails.

They are quite fast for their size, and they could outrun most sloops and schooners (schooners were relatively a lot heavier). The reason is that tall ships could be a lot longer than sloops, giving them a lot of extra hull speed. Sloops couldn't be as large because there weren't strong enough materials available. Try making a single triangular sail with a sail area of over 500 sq. ft. from linen.

So a lot of smaller sails made sense. You could have a large ship with a good maximum hull speed, without your sails ripping apart with every gust of wind.

But you need A LOT of sailors to sail a tall ship: about 30 sailors in total to ie. reef down sails and operate the ship. That's really a lot.

Tall ships are used nowadays for racing, with the popular tall ship races traveling the world. Every four years I go and check them out when they are at Harlingen (which is very close to where I live).

Check out the amazing ships in this video of the tall ship races last year near my hometown. (The event was organized by friends of mine).

What is the difference between a schooner and a sloop? A schooner has two masts, whereas the sloop only has one. The schooner carries more sails, with a mainsail on both masts. Also, sloops are usually Bermuda-rigged, whereas schooners are usually gaff-rigged. Most schooners also carry one or two additional headsails, in contrast to the single jib of the sloop.

What do you call a two-masted sailboat? A two-masted sailboat is most likely a yawl, ketch, schooner, or brig. To determine which one it is you have to locate the mainmast (the tallest). At the rear: schooner or brig. In front: yawl or ketch. Brigs have a square-rigged foremast, schooners don't. Ketches carry a mainsail on the rear mast; yawls don't.

What is a sloop rig? A sloop rig is a sailboat with one mast and two sails: a mainsail and headsail. It's a simple sail plan that handles well and offers good upwind performance. The sloop rig can be sailed shorthanded and is able to sail very close to the wind, making it very popular. Most recreational sailboats use a sloop rig.

What is the difference between a ketch and a yawl? The most important difference between a ketch and a yawl are the position and height of the mizzenmast. The mizzenmast on a yawl is located aft of the rudder, is shorter than the mainmast and doesn't carry a mainsail. On a ketch, it's nearly as long as the mainmast and carries a mainsail.

There are a wonderful lots of DIY changeability shows on the cable airwaves these days.

Rick the rigger

There are SO many errors on this site it really should be taken down.

First major mistake is to say you are no longer afraid of the sea.

One that truly gets up my nose is the term ‘fully’ rigged ship. It’s a FULL rigged ship!! Your mast names are the wrong way round and just because there may be 3 it doesn’t automatically mean the one in the middle is the main.

I could go on and totally destroy your over inflated but fragile ego but I won’t. All I will say is go learn a lot more before posting.

Shawn Buckles

Thanks for your feedback. If you like to point out anything more specific, please let me know and I will update the articles. I’ve changed fully-rigged to full-rigged ship - which is a typo on my part. I try to be as concise as I can, but, obviously, we all make mistakes every now and then. The great thing about the internet is that we can learn from each other and update our knowledge together.

If you want to write yourself and share your knowledge, please consider applying as a writer for my blog by clicking on the top banner.

Thanks, Shawn

Well, I feel that I’ve learned a bit from this. The information is clear and well laid out. Is it accurate? I can’t see anything at odds with the little I knew before, except that I understood a xebec has a square rigged centre mainmast, such as the Pelican ( https://www.adventureundersail.com/ )

Hi, Shawn, You forgot (failed) to mention another type of rig? The oldest type of rig known and still functions today JUNK RIG!

Why are so many of the comments here negative. I think it is wonderful to share knowledge and learn together. I knew a little about the subject (I’m an Aubrey-Maturin fan!) but still found this clarified some things for me. I can’t comment therefore on the accuracy of the article, but it seems clear to me that the spirit of the author is positive. We owe you some more bonhomme I suggest Shawn.

As they say in the Navy: “BZ” - for a good article.

Been reading S.M. Stirling and wanted to understand the ship types he references. Thank you, very helpful.

This site is an awesome starting point for anyone who would like to get an overview of the subject. I am gratefull to Shawn for sharing - Thanks & Kudos to you! If the negative reviewers want to get a deeper technical knowledge that is accurate to the n-th then go study the appropriate material. Contribute rather than destroy another’s good work. Well done Shawn. Great job!

Good stuff Shawn - very helpful. As a novice, it’s too confusing to figure out in bits and pieces. Thanks for laying it out.

First of all I have to say that Rick ‘the rigger’ is obviously the one with the “over inflated but fragile ego” and I laughed when you suggested he share his knowledge on your blog, well played!

As for the content it’s great, hope to read more soon!

Alec Lowenthal

Shawn, I have a painting of a Spanish vessel, two masted, with. Lateen sails on both masts and a jib. The mainsail is ahead of the main mast (fore) and the other is aft of the mizzen mast. Would this be what you call lugger rig? I have not seen a similar picture. Thanks, Alec.

Thank you for your article I found easy to read and understand, and more importantly remember, which emphasises the well written.. Pity about the negative comments, but love your proactive responses!

This vessel, “SEBASTIAN” out of Garrucha, Almería, España, was painted by Gustave Gillman in 1899.

Sorry, picture not accepted!

Thank you for a very informative article. I sail a bit and am always looking for more knowledge. I like the way you put forth your info and I feel if you can’t say anything positive, then that person should have their own blog or keep their opinions to their-self. I will be looking for more from you. I salute your way of dealing with negative comments.

Thank you for a great intro to sailing boats! I searched different sailboats because I use old sails tp make bags and wanted to learn the difference. Way more than I ever expected. Thanks for all the work put in to teach the rest of us.

Your description of a cutter is lacking, and your illustrations of “cutters” are actually cutter-rigged sloops. On a true cutter, the mast is moved further aft (with more than 40% of the ship forward of the mast). A sloop uses tension in the backstay to tension the luff of the foresail. The cutter can’t do this.

Also, a bermuda-rigged ketch will have a line running from the top of the mainmast to the top of the mizzenmast.

wow great guide to rig types! thanks

Interesting guide, however I am confused about the description of the brig. You say the main mast on a brig can have a lateen sail, but in your picture it looks like a gaff sail to me. How is it a lateen sail?

Hi Shawn, thank you for taking the time to share this information. It is clear and very helpful. I am new to sailing and thinking of buying my own blue water yacht. The information you have supplied is very useful. I still am seeking more information on performance and safety. Please keep up the good work. Best Regards

mickey fanelli

I’m starting to repair a model sailboat used in the lake I have three masts that have long been broken off and the sails need replacement. So my question is there a special relationship between the three masts I do have reminents of where the masts should go. they all broke off the boat along with the sails I can figure out where they go because of the old glue marks but it makes no sense. or does it really matter on a model thank you mickey

Cool, total novice here. I have learnt a lot. Thanks for sharing - the diagrams along with the text make it really easy to understand, especially for a beginner who hasn’t even stepped on a sailing boat.

Daryl Beatt

Thank you. Cleared up quite a few things for me. For example, I was familiar with the names “Xebecs” and “Polaccas” from recent reading about the Barbary War. I had gathered that the two Barbary types were better suited to sailing in the Med, but perhaps they were less able to be adaptable to military uses,(but one might assume that would be ok if one plans to board and fight, as opposed to fight a running gun duel). Specifically, the strangely one sided August 1, 1801 battle between the USS Enterprise under Lt. John Sterett and the Polacca cruiser Tripoli under Admiral Rais Mahomet Rous. On paper both ships seemed nearly equal in size, guns and crew, but pictures of the battle are confusing. While the Enterprise is usually rendered as the familiar schooner, the polacca Tripoli has been pictured in radically different ways. Thus the Wikipedia picture by Hoff in 1878 used to illustrate the Battle shows a Brig design for Tripoli, indicating 77 years later, polaccas were no longer common.

Lee Christiansen

I am curious as to what you would call a modern race boat with a fractional jib,not equipped for full masthead hoist? Thanks Lee

Thanks Guy: The information and pictures really eliminate a lot of the mystery of the terminology and the meanings. Also appreciate the insight of the handling idiosyncrasies “hand” (staff) requirements to manage a vessel for one that has not been on the water much. I long to spend significant time afloat, but have concern about the ability to handle a vessel due to advancing age. The Significant Other prefers to sit (in AC comfort)and be entertained by parties of cruise line employees. Thanks again for the information.

‍what is the origin of triangular sails, what is the best shape for a sail, why are most sails triangular, how do triangular sails work, the different types of triangular sails.

We absolutely loved researching this, and we hope you find it as interesting.

The origin of triangular sails can be traced back to ancient maritime history. The use of triangular sails dates back thousands of years and is believed to have originated in the region surrounding the Indian Ocean and the Red Sea.

One of the earliest known civilizations to utilize triangular sails were the ancient Egyptians. They employed triangular-shaped sails on their river vessels known as feluccas, which were used for transportation, trade, and even military purposes along the Nile River. The triangular shape of the sail allowed for effective navigation against the prevailing winds.

Triangular sails were also prevalent in the maritime traditions of other ancient civilizations, including the Phoenicians, Greeks, and Romans. These triangular-shaped sails, known as lateen sails, were extensively used on their ships and played a significant role in the expansion of their naval power and trade networks.

The lateen sail, a type of triangular sail, was particularly prominent in the Mediterranean region. It offered numerous advantages such as better maneuverability, improved windward performance, and the ability to sail closer to the wind compared to square sails.

The lateen sail continued to be used by various civilizations and cultures throughout history, including the Arab dhows, Byzantine ships, and medieval European vessels like the carrack and caravel.

The triangular sail design spread to other parts of the world through exploration, trade, and cultural exchange. It influenced the sailing practices of different maritime civilizations, including the Chinese junks, Polynesian voyaging canoes, and Viking longships.

Over time, as sailing technology and sailmaking techniques advanced, other sail configurations such as square sails and more complex combinations of triangular and square sails emerged.

However, the triangular sail remains an iconic and enduring design that continues to be used in modern sailboats, particularly in various forms of small recreational sailboats, racing yachts, and even some larger cruising vessels.

Today, triangular sails are still appreciated for their efficiency, versatility, and ability to harness the power of the wind effectively. The legacy of the ancient sailors who first employed these sails lives on, and the triangular sail design remains an integral part of sailing heritage and tradition.

Sails, with their billowing shapes and graceful forms, have long been an essential component of sailing vessels. They harness the power of the wind, propelling boats across the water with elegance and efficiency.

But have you ever wondered why sails are predominantly triangular in shape? What makes the triangular sail design so prevalent and effective in the world of sailing?

Determining the “best” shape for a sail depends on various factors, including the type of vessel, sailing conditions, and desired performance characteristics. Different sail shapes are designed to optimize performance in specific wind angles and conditions.

Here are a few common sail shapes and their typical uses:

Triangular (Bermudan) Sail: Triangular sails, such as the mainsail and jib, are widely used on modern sailboats. They offer versatility, good windward performance, and ease of adjustment. The shape of triangular sails can be adjusted by controlling the tension of the sail’s control lines, allowing sailors to optimize the sail shape for different wind conditions.
Square Sail: Square sails are large, four-cornered sails that were historically used on tall ships and traditional sailing vessels. They excel in downwind sailing, taking advantage of following winds. Square sails are not as effective for windward sailing and require additional sails or adjustments to achieve better performance across different wind angles.
Gaff Sail: Gaff sails have a four-sided shape with a gaff, a spar that extends horizontally from the top of the mast , providing additional sail area. Gaff sails were commonly used on traditional working boats. They offer good downwind performance and are relatively easy to handle, making them suitable for cruising and recreational sailing.
Catamaran/Racing Sails: For high-performance racing catamarans or multihulls, the sails are often designed with a more specialized shape. These sails are built to generate maximum power, utilizing a more pronounced curvature or “draft” to optimize lift and speed. Racing sails for high-performance monohulls also prioritize shape and performance, focusing on reducing drag and maximizing power efficiency.

It’s important to note that sail shapes can be further modified by adjusting factors such as sail trim, halyard tension, sheet tension, and control line settings. The optimal sail shape for a given situation may vary based on wind strength, wind angle, and the desired speed or maneuverability.

Ultimately, the “best” sail shape depends on the specific requirements of the sailor, the vessel’s design, and the intended use.

Sailors often consult with sailmakers (we learned so much from meeting the sail designer at Precision Sails – it’s well worth contacting them just for the chat!) or rely on their own experience and experimentation to find the ideal balance of sail shape, trim, and performance for their sailing needs.

Most sails are triangular because this design offers several advantages in terms of performance, versatility, and ease of use. Here are a few reasons why triangular sails are commonly used:

Aerodynamic Efficiency

Triangular sails, such as the mainsail and jib, are aerodynamically efficient. The shape allows the wind to flow smoothly over the curved surface, generating lift and propelling the boat forward.

The triangular shape helps create a desirable flow pattern and reduces turbulence, resulting in improved overall efficiency and performance.

This is where the aeroplane wing image comes in handy. It’s not the easiest concept to understand, but once you do it’s really fascinating. It’s hard to imagine how people ever discovered it!

Versatility

Triangular sails are versatile and can be adjusted to suit various wind conditions and points of sail. By adjusting the control lines, sailors can alter the shape of the triangular sail to optimize performance across a range of wind angles, from upwind (close-hauled) to reaching and downwind sailing.

Let’s take a further look at the advantages they give to upwind sailing!

Windward Performance

Triangular sails perform well when sailing upwind (close-hauled) or at an angle to the wind. Their shape allows sailors to trim the sail close to the wind, generating lift and propelling the boat forward efficiently.

The ability to point relatively high into the wind is crucial for racing sailboats and maximizing efficiency when sailing to windward.

There are other factors that come into play when using triangular sails to sail upwind, like the keel of a sailboat, but triangular sails were kind of revolutionary in allowing sailboats to sail more than just downwind.

Maneuverability

Triangular sails provide excellent maneuverability. By adjusting the control lines, sailors can quickly depower or reef the sail, reducing its area and adjusting the shape to handle stronger winds or gusts.

This ability to easily adjust sail shape and size contributes to the overall control and safety of the vessel.

Triangular sails are relatively simple to construct, rig, and handle. They require fewer spars and rigging components compared to other sail shapes, reducing complexity and potential points of failure.

This simplicity makes triangular sails popular among recreational sailors and cruisers who prioritize ease of use and maintenance. It can also affect how long new sails last.

It also makes them cheaper to manufacture and therefore cheaper to buy than more complex sail shapes.

Historical Tradition

As we just explored, the use of triangular sails has a long historical tradition that extends back to ancient maritime cultures. Over centuries of seafaring, the triangular sail design has proven its efficiency and versatility, contributing to its enduring popularity and widespread adoption.

While other sail shapes, such as square sails and gaff sails, have their own advantages in specific sailing conditions, triangular sails have become the standard for modern sailing vessels due to their overall performance, adaptability, and historical precedent.

the mainsail of a sailboat, looking up at it

Triangular sails work based on the principles of aerodynamics, utilizing the interaction between wind and the curved shape of the sail to generate lift and propel a sailing vessel forward.

Here’s a breakdown of how triangular sails work (we’ve tried to keep it simple!):

Lift Generation: When the wind blows against a triangular sail, it splits into two airflows, one flowing above the sail and the other flowing beneath it.

The curved shape of the sail, known as the airfoil, creates different air pressures on each side.

The air moving across the curved surface of the sail has a longer distance to travel compared to the air passing beneath the sail, creating a pressure differential.

This pressure difference generates lift, similar to how an airplane wing generates lift to stay airborne.

Angle of Attack: The angle at which the wind strikes the sail is crucial for generating lift. By trimming or adjusting the sail, sailors can control the angle of attack, which is the angle between the sail’s surface and the direction of the oncoming wind.

By trimming the sail closer to the wind, sailors can maximize the lift and propulsion generated by the sail.

Point of Sail: Triangular sails can be adjusted to optimize performance at different points of sail.

When sailing upwind (close-hauled), the sail is trimmed in tightly, with the leading edge (luff) of the sail as close to the wind as possible, creating a high-pressure area on the windward side of the sail. This generates lift and propels the boat forward.

When sailing off the wind, the sail is eased out, allowing the wind to flow across the sail’s curved surface and generate lift while maintaining control and balance.

Sail Controls: Sail controls, such as the halyard, sheets, and control lines, allow sailors to adjust the shape and tension of the triangular sail.

Tensioning the halyard raises the sail to its desired height on the mast, while the sheets control the angle and trim of the sail.

Additional control lines, such as the cunningham and outhaul, allow sailors to fine-tune the shape and control the draft of the sail, optimizing performance in different wind conditions.

Depowering: In strong winds or gusts, sailors can depower the triangular sail by easing the sheets and flattening the sail’s shape. You can also reef the sail and keep the triangular shape the same, but with less sail area to catch the wind.

This reduces the sail’s overall area and curvature, minimizing the lift and power generated, thus making the sail more manageable in higher wind speeds.

Understanding and manipulating these factors of sail trim, angle of attack, and sail controls allow sailors to harness the power of the wind and optimize the performance of their triangular sails.

By adjusting the sail’s shape and position in response to wind and course changes, sailors can achieve efficient propulsion and maneuverability, allowing them to sail effectively across a wide range of wind angles and conditions.

There are several different types of triangular sails commonly used in sailing. These sails vary in size, position, and purpose, and each plays a specific role in the overall sail plan of a sailing vessel.

Here are some of the main types:

The mainsail is the primary and largest triangular sail on most sailing vessels. It is typically positioned behind the mast and spans from the mast to the boom.

The mainsail provides the primary driving force for propulsion and is highly adjustable using control lines such as the halyard, boom vang, mainsheet, and reefing lines.

The mainsail is used for powering the boat in various points of sail, from close-hauled (upwind) to reaching and downwind angles.

The jib sail is a triangular sail that is located forward of the mast. It is attached to the forestay, a wire or rod that extends from the mast to the bow of the boat.

The jib works in conjunction with the mainsail and is primarily used for upwind sailing. It helps to balance the forces generated by the mainsail and assists in pointing the boat closer to the wind.

Jibs come in different sizes, such as genoas (larger overlap jibs) and working jibs (smaller storm sails used in heavier winds).

A genoa is a large, overlapping jib that extends beyond the mast and overlaps with the mainsail.

Genoas provide additional sail area and are used when sailing off the wind or in light to moderate winds. They enhance the sail area and power of the sail plan, increasing the overall speed and performance of the vessel.

We love to use our Genoa alone for downwind sailing.

The Spinnaker is a specialized downwind sail that is typically shaped like a large, colorful balloon. It is designed to catch wind from behind the boat and is used for sailing downwind or at broad reaching angles.

Spinnakers are often used in racing and cruising for faster downwind sailing and can provide a significant boost in speed. They require additional rigging and control lines, such as the spinnaker halyard, sheets, and guys.

The Code Zero is a specialized headsail that combines the characteristics of a genoa and a spinnaker. It is typically used for light to moderate wind angles and provides enhanced performance on reaching angles.

Code Zeros have a flatter shape and are often used on performance-oriented boats to optimize speed when sailing off the wind.

These are just a few examples of the different types of triangular sails commonly used in sailing.

Each sail serves a specific purpose and can be adjusted and combined with other sails to optimize performance across various wind conditions and points of sail. Sailors often tailor their sail combinations based on factors such as wind strength, boat design, and intended course or race strategy.

Conclusion: Why Are Sails Triangular

In conclusion, triangular sails are widely used in sailing due to their aerodynamic efficiency, versatility, and historical tradition.

The triangular shape of these sails allows for effective lift generation and propulsion when the wind flows over their curved surfaces. By adjusting the angle of attack and sail controls, sailors can optimize their performance across different wind angles and points of sail.

Triangular sails, such as the mainsail, jib, genoa, spinnaker, and Code Zero, each have specific roles and purposes within a sail plan, allowing sailors to adapt to various wind conditions and sail efficiently.

The simplicity of construction, ease of use, and historical precedence have contributed to the enduring popularity of triangular sails in both recreational and competitive sailing.

As sailing technology advances, the triangular sail remains a fundamental and effective design for harnessing the power of the wind and propelling sailing vessels across the water.

Whether you're a proud owner of one, a guest on one, or a shore-side admirer, you'll fall in love with the gliding sails, the excitement of a race, and the eco-friendly nature of these sophisticated yet magnificent vessels. With good sails, great design, and regular maintenance, sails and rigs are an important part of a sailboat.

If you’re thinking about going sailing, one of the first things you have to understand is the variety of modern sail plans. Unlike old sailboats, modern sailboats don't need huge, overlapping headsails and multiple masts just to get moving. In the past, when sailboats were heavy, keels were long, the only way to get the boat moving was with a massive relative sail area. You needed as much square footage as you could just to get your sailboat moving. But with the invention of fiberglass hulls, aluminum or composite masts, high-tensile but low diameter lines and stats, and more efficient sails, sailboats no longer need to plan for such large sail plans.. Still, there are various rig styles, from the common sloop, to the comfortable cat-rig, to the dual masted ketch and schooner, there are various sail types and rigs to choose from. The most important thing is to know the different types of sails and rigs and how they can make your sailing even more enjoyable.

There are different types of sails and rigs. Most sailboats have one mainsail and one headsail. The mainsail is generally fore-and-aft rigged and is triangular shaped. Various conditions and courses require adjustments to the sails on the boats, and, other than the mainsail, most boats can switch out their secondary sail depending on various conditions.. Do you want to sail upwind or go downwind? You cannot hoist just any sail and use it. It's, therefore, of great importance to understand how and when to use each sail type.

In this in-depth article, we'll look at various sail types and rigs, and how to use them to make your sailing more enjoyable.

Different Sail Types

It is perhaps worth noting that a sailboat is only as good as its sails. The very heart of sailing comes in capturing the wind using artfully trimmed sails and turning that into motion. . Ask any good sailor and he'll tell you that knowing how and when to trim the sails efficiently will not only improve the overall performance of your boat but will elevate your sailing experience. In short, sails are the driving force of sailboats.

As such, it's only natural that you should know the different types of sails and how they work. Let's first highlight different sail types before going into the details.

Jib - triangular staysail
Spinnaker - huge balloon-shaped downwind sail for light airs
Genoa - huge jib that overlaps the mainsail
Gennaker - a combination of a spinnaker and genoa
Code zero - reaching genoa for light air
Windseeker - tall, narrow, high-clewed, and lightweight jib
Drifter - versatile light air genoa made from particularly lightweight cloth
Storm jib - a smaller jib meant for stormy conditions
Trysail - This is a smaller front-and-aft sail for heavy weather

The mainsail is the principal sail on a boat. It's generally set aft of the mainmast. Working together with the jib, the mainsail is designed to create the lift that drives the sailboat windward. That being said, the mainsail is a very powerful component that must always be kept under control.

As the largest sail, and the geometric center of effort on the boat, the mainsail is tasked with capturing the bulk of the wind that's required to propel the sailboat. The foot, the term for the bottom of any sail, secures to the boom, which allows you to trim the sail to your heading. The luff, the leading edge of the sail, is attached to the mast. An idealized mainsail would be able to swing through trim range of 180°, the full semi-circle aft of the mast, though in reality, most larger boats don’t support this full range of motion, as a fully eased sail can occasionally be unstable in heavy breeze.

. As fully controlling the shape of the mainsail is crucial to sailing performance, there are many different basic mainsail configurations. For instance, you can get a full-batten mainsail, a regular mainsail with short battens, or a two-plus-two mainsail with two full-length battens. Hyper-high performance boats have even begun experimenting with winged sails which are essentially trimmable airplane wings! Moreover, there are numerous sail controls that change the shape by pulling at different points on the sail, boom, or mast. Reefing, for instance, allows you to shorten the sail vertically, reducing the amount of sail area when the boat is overpowered.

Features of a Mainsail

Several features will affect how a particular sail works and performs. Some features will, of course, affect the cost of the sail while others may affect its longevity. All in all, it's essential to decide the type of mainsail that's right for you and your sailing application.

Sail Battens, the Roach, and the Leech

The most difficult part of the sail to control, but also the most important, are the areas we refer to as the leech and the roach. The roach is the part of the sail that extends backwards past the shortest line between the clew, at the end of the boom, and the top of the mast. It makes up roughly the back third of the sail. The leech is the trailing edge of the sail, the backmost curve of the roach. Together, these two components control the flow of the air off the back of the sail, which greatly affects the overall sail performance. If the air stalls off the backside of the sail, you will find a great loss in performance. Many sail controls, including the boom vang, backstay, main halyard, and even the cunningham, to name a few, focus on keeping this curve perfect.

As for parts of the sail itself, battens control the overall horizontal shape of the sail. Battens are typically made from fiberglass or wood and are built into batten pockets. They're meant to offer support and tension to maintain the sail shape Depending on the sail technology you want to use, you may find that full battens, which extend from luff to leech, or short battens, just on the trailing edge, are the way to go. Fully battened sails tend to be more expensive, but also higher performance.

Fully Battened Mainsails

They're generally popular on racing multihulls as they give you a nice solid sail shape which is crucial at high speeds. In cruising sailboats , fully battened mainsails have a few benefits such as:

They prevent the mainsail from ragging. This extends the life of the sail, and makes maneuvers and trimming easier for the crew.
It provides shape and lift in light-air conditions where short-battened mainsails would collapse.

On the other hand, fully-battened mainsails are often heavier, made out of thicker material, and can chafe against the standing rigging with more force when sailing off the wind.

Short Battens

On the other hand, you can choose a mainsail design that relies mostly on short battens, towards the leech of the sail. This tends to work for lighter cloth sails, as the breeze, the headsail, and the rigging help to shape the sail simply by the tension of the rig and the flow of the wind. The battens on the leech help to preserve the shape of the sail in the crucial area where the air is flowing off the back of the sail, keeping you from stalling out the entire rig.

The only potential downside is that these short battens deal with a little bit of chafe and tension in their pockets, and the sail cloth around these areas ought to be reinforced. If your sails do not have sufficient reinforcement here, or you run into any issues related to batten chafe, a good sail maker should be able to help you extend the life of your sails for much less than the price of a new set.

How to Hoist the Mainsail

Here's how to hoist the mainsail, assuming that it relies on a slab reefing system and lazy jacks and doesn't have an in-mast or in-boom furling system.

‍Maintain enough speed for steeragewhile heading up into the wind
Slacken the mainsheet, boom vang, and cunningham
Make sure that the lazy jacks do not catch the ends on the battens by pulling the lazy jacks forward.
Ensure that the reefing runs are free to run and the proper reefs are set if necessary.
Raise the halyard as far as you can depending on pre-set reefs.
Tension the halyard to a point where a crease begins to form along the front edge
Re-set the lazy jacks
Trim the mainsail properly while heading off to your desired course

So what's Right for You?

Your mainsail will depend on how you like sailing your boat and what you expect in terms of convenience and performance. That being said, first consult the options that the boatbuilder or sailmakers suggest for your rig. When choosing among the various options, consider what you want from the sail, how you like to sail, and how much you're willing to spend on the mainsail.

The headsail is principally the front sail in a fore-and-aft rig. They're commonly triangular and are attached to or serve as the boat’s forestay. They include a jib and a genoa.

A jib is a triangular sail that is set ahead of the foremost sail. For large boats, the roto-furling jib has become a common and convenient way to rig and store the jib. Often working in shifts with spinnakers, jibs are the main type of headsails on modern sailboats. Jibs take advantage of Bournoulli’s Principle to break the incoming breeze for the mainsail, greatly increasing the speed and point of any boat. By breaking the incoming wind and channeling it through what we call the ‘slot,’ the horizontal gap between the leech of the jib and the luff of the mainsail, the jib drastically increases the efficiency of your mainsail. It additionally balances the helm on your rudder by pulling the bow down, as the mainsail tends to pull the stern down. .

The main aim of the jib is to increase the sail area for a given mast size. It improves the aerodynamics of the mainsails so that your sailboat can catch more wind and thereby sail faster, especially in light air

Using Jibs on Modern Sailboats

In the modern contexts, jib’s mainly serve increase the performance and overall stability of the mainsail. The jib can also reduce the turbulence of the mainsail on the leeward side.

On Traditional Vessels

Traditional vessels such as schooners have about three jibs. The topmast carried a jib topsail, the main foresail is called the jib, while the innermost jib is known as the staysail. The first two were employed almost exclusively by clipper ships.

How to Rig the Jibs

There are three basic ways to rig the jib.

Track Sheets - A relatively modern approach to the self-tacking jib, this entails placing all the trimming hardware on a sliding track forward of the mast. This means that on each tack, the hardware slides from one side of the boat to the other. This alleviates the need to switch sheets and preserves the trim angle on both sides, though it can be finnicky and introduce friction.

Sheet up the Mast - This is a very popular approach and for a good reason. Hoist the jib sheet up the mast high enough to ensure that there's the right tension through the tack. Whether internally or externally, the sheet returnsto the deck and then back to the cockpit just like the rest of the mast baselines. The fact the hardware doesn't move through the tacks is essential in reducing friction.

Sheet Forward - This method revolves around ensuring that the jib sheet stays under constant pressure so that it does not move through the blocks in the tacks. This is possible if the through-deck block is extremely close to the jib tack. Your only challenge will only be to return the sheet to the cockpit. This is, however, quite challenging and can cause significant friction.

Dual Sheeting - The traditional method, especially on smaller dinghies, though it is not self-tacking. This requires a two ended or two separate sheet system, where one sheet runs to a block on starboard, and the other to port. Whenever you tack or gybe, this means you have to switch which sheet is active and which is slack, which is ok for well crewed boats, but a potential issue on under-crewed boats.

Another important headsail, a genoa is essentially a large jib that usually overlaps the mainsail or extends past the mast, especially when viewed from the other side. In the past, a genoa was known as the overlapping jib and is technically used on twin-mast boats and single-mast sloops such as ketches and yawls. A genoa has a large surface area, which is integral in increasing the speed of the vessel both in moderate and light winds.

Genoas are generally characterized by the percentage they cover. In most cases, sail racing classes stipulate the limit of a genoa size. In other words, genoas are usually classified by coverage.

Top-quality genoa trim is of great importance, especially if the wind is forward of the beam. This is because the wind will first pass over the genoa before the mainsail. As such, a wrongly sheeted genoa can erroneously direct the wind over the mainsail,spelling doom to your sailing escapades. While you can perfectly adjust the shape of a genoa using the mast rake, halyard tension, sheet tension, genoa car positioning, and backstay tension, furling and unfurling a genoa can be very challenging, especially in higher winds.

That being said, here are the crucial steps to always keep in mind.

Unload and ease the loaded genoa sheet by going to a broad reach
Do not use the winch; just pull on the furling line
Keep a very small amount of pressure or tension on the loaded genoa sheet
Secure the furling line and tighten the genoa sheets
Get on the proper point of sail
Have the crew help you and release the lazy genoa sheets
Maintain a small tension while easing out the furling line
Pull-on a loaded genoa sheet
Close or cleat off the rope clutch when the genoa is unfurled
Trim the genoa

To this end, it's important to note that genoas are popular in some racing classes. This is because they only categorize genoas based on the fore-triangle area covered, which essentially allows a genoa to significantly increase the actual sail area. On the contrary, keep in mind that tacking a genoa is quite a bit harder than a jib, as the overlapping area can get tangled with the mast and shrouds. It's, therefore, important to make sure that the genoa is carefully tended, particularly when tacking.

Downwind Sails

Modern sailboats are a lot easier to maneuver thanks to the fore-and-aft rig. Unfortunately, when sailing downwind they catch less wind, and downwind sails are a great way of reducing this problem. They include the spinnaker and the gennaker.

A spinnaker will, without a doubt, increase your sailing enjoyment. But why are they often buried in the cabin of cruising boats? Well, the first few attempts to rig and set a spinnaker can be difficult without enough help and guidance. Provided a solid background, however, spinnakers are quite straightforward and easy to use and handle with teamwork and enough practice. More importantly, spinnakers can bring a light wind passage to life and can save your engine.

Spinnakers are purposely designed for sailing off the wind; they fill with wind and balloon out in front of your sailboat. Structured with a lightweight fabric such as nylon, the spinnaker is also known as a kite or chute, as they look like parachutes both in structure and appearance.

A perfectly designed spinnaker should have taut leading edges when filled. This mitigates the risk of lifting and collapsing. A spinnaker should have a smooth curve when filled and devoid of depressions and bubbles that might be caused by the inconsistent stretching of the fabric. The idea here is that anything other than a smooth curve may reduce the lift and thereby reduce performance.

Types of Spinnakers

There are two main types of spinnakers: symmetric spinnakers and asymmetric spinnakers.

Asymmetric Spinnakers

Flown from a spinnaker pole or bowsprit fitted to the bow of the boat, asymmetric spinnakers resemble large jibs and have been around since the 19th century. The concept of asymmetric spinnaker revolves around attaching the tack of the spinnaker at the bow and pulling it around during a gybe.

Asymmetric spinnakers have two sheets just like a jib., These sheets are attached at the clew and never interact directly with the spinnaker pole. This is because the other corner of the spinnaker is fixed to the bowsprit. The asymmetric spinnaker works when you pull in one sheet while releasing the other. This makes it a lot easier to gybe but is less suited to sailing directly downwind. There is the loophole of having the asymmetric spinnaker gybed to the side opposite of the boom, so that the boat is sailing ‘wing-on-wing,’ though this is a more advanced maneuver, generally reserved for certain conditions and tactical racing situations.

On the contrary, the asymmetric spinnaker is perfect for fast planing dinghies. This is because such vessels have speeds that generate apparent wind forward. Because asymmetrics, by nature, prefer to sail shallower downwind angles, this apparent wind at high speeds makes the boat think that it is sailing higher than it really is, allowing you to drive a little lower off the breeze than normal. . In essence, the asymmetric spinnaker is vital if you're looking for easy handling.

Symmetric Spinnakers

Symmetric spinnakers are a classic sail type that has been used for centuries for controlling boats by lines known as a guy and a sheet. The guy, which is a windward line, is attached to the tack of the sail and stabilized by a spinnaker pole. The sheet, which is the leeward line, is attached to the clew of the spinnaker and is essential in controlling the shape of the spinnaker sail.

When set correctly, the leading edges of the symmetric spinnaker should be almost parallel to the wind. This is to ensure that the airflow over the leading edge remains attached. Generally, the spinnaker pole should be at the right angles to the apparent wind and requires a lot of care when packing.

The main disadvantage of this rig is the need to gybe the spinnaker pole whenever you gybe the boat. This is a complicated maneuver, and is one of the most common places for spinnakers to rip or get twisted. If, however, you can master this maneuver, you can sail at almost any angle downwind!

How to Use Spinnaker Effectively

If you decide to include the spinnakers to your sailboat, the sailmaker will want to know the type of boat you have, what kind of sailing you do, and where you sail. As such, the spinnaker that you end up with should be an excellent and all-round sail and should perform effectively off the breeze

The type of boat and where you'll be sailing will hugely influence the weight of your spinnaker cloth. In most cases, cruising spinnakers should be very light, so if you've decided to buy a spinnaker, make sure that it's designed per the type of your sailboat and where you will be sailing. Again, you can choose to go for something lighter and easier to set if you'll be sailing alone or with kids who are too young to help.

Setting up Spinnakers

One of the main reasons why sailors distrust spinnakers is because they don't know how to set them up. That being said, a perfectly working spinnaker starts with how you set it up and this revolves around how you carefully pack it and properly hook it up. You can do this by running the luff tapes and ensuring that the sails are not twisted when packed into the bag. If you are using large spinnakers, the best thing to do is make sure that they're set in stops to prevent the spinnakers from filling up with air before you even hoist them fully.

But even with that, you cannot fully set the spinnaker while sailing upwind. Make sure to bear away and have your pole ready to go as you turn downwind. You should then bear away to a reach before hoisting. Just don't hoist the spinnakers from the bow as this can move the weight of the crew and equipment forward.

Used when sailing downwind, a gennaker is asymmetric sail somewhere between a genoa and a spinnaker. It sets itself apart because it gennaker is a free-flying asymmetric spinnaker but it is tacked to the bowsprit like the jib.

Let's put it into perspective. Even though the genoa is a great sail for racing and cruising, sailors realized that it was too small to be used in a race or for downwind sail and this is the main reason why the spinnaker was invented. While the spinnakers are large sails that can be used for downwind sail, they are quite difficult to handle especially if you're sailing shorthanded. As such, this is how a gennaker came to be: it gives you the best of both worlds.

Gennakers are stable and easy to fly and will add to your enjoyment and downwind performance.

The Shape of a Gennaker

As we've just noted, the gennaker is asymmetrical. It doesn't attach to the forestay like the genoa but has a permanent fitting from the mast to bow. It is rigged exactly like a spinnaker but its tack is fastened to the bowsprit. This is fundamentally an essential sail if you're looking for something to bridge the gap between a genoa and a spinnaker.

Setting a Gennaker

When cruising, the gennaker is set with the tack line from the bow, a halyard, and a sheet that's led to the aft quarter. Attach the tack to a furling unit and attach it to a fitting on the hull near the very front of the sailboat. You can then attach the halyard that will help in pulling it up to the top of the mast before attaching it to the clew. The halyard can then run back to the winches to make the controlling of the sail shape easier, just like when using the genoa sail.

In essence, a gennaker is a superb sail that will give you the maximum versatility of achieving the best of both a genoa and a spinnaker, especially when sailing downwind. This is particularly of great importance if you're cruising by autopilot or at night.

Light Air Sails

Even though downwind sails can be used as light air sails, not all light air sails can be used for downwind sailing. In other words, there's a level of difference between downwind sails and light air sails. Light air sails include code zero, windseeker, and drifter reacher.

A cross between an asymmetrical spinnaker and a genoa, a code zero is a highly modern sail type that's generally used when sailing close to the wind in light air. Although the initial idea of code zero was to make a larger genoa, it settled on a narrow and flat spinnaker while upholding the shape of a genoa.

Modern boats come with code zero sails that can be used as soon as the sailboat bears off close-hauled even a little bit. It has a nearly straight luff and is designed to be very flat for close reaching. This sail is designed to give your boat extra performance in light winds, especially in boats that do not have overlapping genoas. It also mitigates the problem of loss of power when you are reaching with a non-overlapping headsail. Really, it is closer to a light air jib that sacrifices a little angle for speed.

In many conditions, a code zero sail can go as high as a sailboat with just a jib. By hoisting a code zero, you'll initially have to foot off about 15 degrees to fill it and get the power that you require to heel and move the boat. The boat will not only speed up but will also allow you to put the bow up while also doing the same course as before you set the zero. In essence, code zero can be an efficient way of giving your boat about 30% more speed and this is exactly why it's a vital inventory item in racing sailboats.

When it comes to furling code zero, the best way to do it is through a top-down furling system as this will ensure that you never get a twist in the system.

Generally used when a full size and heavier sail doesn't stay stable or pressurized, a windseeker is a very light sail that's designed for drifting conditions. This is exactly why they're designed with a forgiving cloth to allow them to handle these challenging conditions.

The windseeker should be tacked at the headstay with two sheets on the clew. To help this sail fill in the doldrums, you can heel the boat to whatever the apparent leeward side is and let gravity help you maintain a good sail shape while reaching.The ideal angle of a windseeker should be about 60 degrees.

Though only used in very specific conditions, the windseeker is so good at this one job that it is worth the investment if you plan on a long cruise. Still, you can substitute most off the breeze sails for this in a pinch, with slightly less performance gain, likely with more sacrifices in angle to the breeze.

Drifter Reacher

Many cruising sailors often get intimidated by the idea of setting and trimming a drifter if it's attached to the rig at only three corners or if it's free-flying. But whether or not a drifter is appropriate for your boat will hugely depend on your boat's rig, as well as other specific details such as your crew's ability to furl and unfurl the drifter and, of course, your intended cruising grounds.

But even with that, the drifter remains a time-honored sail that's handy and very versatile. Unlike other light air sails, the drifter perfectly carries on all points of sails as it allows the boat to sail close-hauled and to tack. It is also very easy to control when it's set and struck. In simpler terms, a drifter is principally a genoa that's built of lightweight fabric such as nylon. Regardless of the material, the drifter is a superb sail if you want to sail off a lee shore without using the genoa.

Generally stronger than other regular sails, stormsails are designed to handle winds of over 45 knots and are great when sailing in stormy conditions. They include a storm jib and a trysail.

If you sail long and far enough, chances are you have or will soon be caught in stormy conditions. Under such conditions, storm jibs can be your insurance and you'll be better off if you have a storm jib that has the following features:

Robustly constructed using heavyweight sailcloth
Sized suitably for the boat
Highly visible even in grey and white seas

That's not all; you should never go out there without a storm jib as this, together with the trysail, is the only sails that will be capable of weathering some of nature's most testing situations.

Storm jibs typically have high clews to give you the flexibility of sheet location. You can raise the sail with a spare halyard until its lead position is closed-hauled in the right position. In essence, storm jib is your insurance policy when out there sailing: you should always have it but always hope that you never have to use it.

Also known as a spencer, a trysail is a small, bright orange, veritably bullet-proof, and triangular sail that's designed to save the boat's mainsail from winds over 45 knots and works in the same way as a storm jib. It is designed to enable you to make progress to windward even in strong and stormy winds.

Trysails generally use the same mast track as the mainsail but you have to introduce the slides into the gate from the head of the trysail.

There are two main types of rigs: the fore-and-aft rig and the square rigg.

Fore-and-aft Rig

This is a sailing rig that chiefly has the sails set along the lines of the keel and not perpendicular to it. It can be divided into three categories: Bermuda rig, Gaff rig, and Lateen rig.

Bermuda Rig - Also known as a Marconi rig, this is the typical configuration of most modern sailboats. It has been used since the 17th century and remains one of the most efficient types of rigs. The rig revolves around setting a triangular sail aft of the mast with the head raised to the top of the mast. The luff should run down the mast and be attached to the entire length.

Gaff Rig - This is the most popular fore-and-aft rig on vessels such as the schooner and barquentine. It revolves around having the sail four-cornered and controlled at its peak. In other words, the head of the mainsail is guided by a gaff.

Lateen Rig - This is a triangular fore-and-aft rig whereby a triangular sail is configured on a long yard that's mounted at a given angle of the mast while running in a fore-and-aft direction. Lateen rig is commonly used in the Indian Ocean and the Mediterranean.

Square Rigged

This is a rig whereby the mainsails are arranged in a horizontal spar so that they're square or vertical to the mast and the keel of the boat. The square rig is highly efficient when sailing downwind and was once very popular with ocean-going sailboats.

Unquestionably, sailing is always pleasurable. Imagine turning off the engine of your boat, hoisting the sails, and filling them with air! This is, without a doubt, a priceless moment that will make your boat keel and jump forward!

But being propelled by the noiseless motion of the wind and against the mighty currents and pounding waves of the seas require that you know various sail types and how to use them not just in propelling your boat but also in ensuring that you enjoy sailing and stay safe. Sails are a gorgeous way of getting forward. They remain the main fascination of sailboats and sea cruising. If anything, sails and boats are inseparable and are your true friends when out there on the water. As such, getting to know different types of sails and how to use them properly is of great importance.

All in all, let's wish you calm seas, fine winds, and a sturdy mast!

I've personally had thousands of questions about sailing and sailboats over the years. As I learn and experience sailing, and the community, I share the answers that work and make sense to me, here on Life of Sailing.

Names of Sails on a Sailboat

Are you a beginner sailor and want to get acquainted with the names of the sails? Are you an experienced sailor and want to learn more details about the sails on a sailboat? Then this article is written for you! Sails form a crucial part of the sailboat because without them, there’s no starting up. For that reason, there are many details about different types of sails concerning their utility, functionality, fabrication materials, and performance. Simply put, each sail serves different purposes when out on the water. Since the sail is the engine of your sailboat, in terms of it being the basic source of propulsion, it’s important to know when best to use either type of sail and why.

Types of Sails on a Sailboat

So, in order to better explain the types of sails, let’s look at their characteristics. The first important distinction between sails is their placement. Generally, the mainsail is placed aft of the mast , which means behind. On the contrary, the headsail is in front of the mast. There are also other sorts of sails that are used for specific conditions. These can be the spinnakers or balloon-shaped sails for downwind use. The second important distinction for the sails is their functionality. The specialized sails have different functionalities and are used in different sailing circumstances and weather conditions. A rule about sails is that large sails are appropriate for downwind use, whereas small sails are good for upwind use. Moreover, large sails perform better on weak winds while small sails are good for strong winds.

The Parts of a Sail and its Shapes

Head: This is the top of the sail.
Luff: The forward edge of the sail.
Leech: Back edge of the sail.
Tack: The lower front corner of the sail.
Clew: The bottom back corner of the sail.
Foot: Bottom of the sail.

There are two sail shapes, the fore-and-aft rigged sails, and square-rigged sails. Nowadays, fore-and-aft sails are more popular, have better performance and maneuverability. To grasp the idea square sails are the ones that Vikings had on their ships and are good at sailing downwind because they run from side to side. But they’re not suitable at all when sailing upwind. On the other hand, a fore-and-aft sail is tied from the front of the mast to the stern and is much better at sailing upwind.

Types and Names of Sails

There are a lot of reasons why you’d want to put one sail over another, but the most important thing to remember has to do with the point of your sail and the wind strength. These points help you understand how your sailboat generates wind power. These points of sail include: into the wind (in irons), beam-reaching, broad-reaching, close-hauled, close-reaching, and running. They all go from windward to leeward and are symmetric from port to starboard . So, let’s get to the point and see the names and explanation of each sail:

Mainsail : The large sail behind the mast which is attached to the mast and the boom, is called the mainsail. Mainsails cover a lot of surface area concerning incoming winds and by doing that they don’t need very strong winds to provide forward propulsion on a sailboat.
Headsail or Jib : The small sail placed in front of the mast, attached to the mast and forestay (ie. jib or genoa), is called the headsail. Headsails are smaller than mainsails, thus their surface area is smaller. As a result, they can’t catch the same wind as a mainsail does. However, this is important because in case that the current wind is strong and the mainsail has been enough trimmed, being able to remove the mainsail and depend on the headsail alone, is a good strategy in order to reduce speed.
Genoa : A genoa is like a large jib and it’s attached to the front of the forestay, like a headsail. When you use a genoa sail then you are expecting light to medium winds. Also, your sailboat would be somehow in a rush point of sail, meaning that the wind comes directly from the rear. Moreover, the surface area of a genoa sail is quite large, so it’s important to use it when winds are relatively low.
Spinnaker : These downwind sails are symmetrical which makes them more sensitive to the reaching points of the sail and therefore more suitable for the running point of sail. Spinakkers are lighter than other types of jibs, and they don’t cover the mast like a genoa sail. Moreover, they remain unattached to the forestay and stretch out toward and past the bow of a sailboat.
Gennaker : Gennakers are a mixture of genoa and spinnaker sails. There are small and big gennakers and both are downwind sails. They aren’t as symmetric as a spinnaker and aren’t attached to the forestay like a headsail. Furthermore, the gennaker sail is able to take on a more flexible point of sail while taking advantage of softer winds.
Drifter Reacher : A drifter is a light air sail, and it’s basically a larger genoa for use in light winds. Its extra sail area offers better downwind performance than a genoa. It’s mostly made from lightweight nylon.
Code Zero Reacher : This sail is a type of spinnaker, but it looks like a large genoa. However, code zero is designed for better reaching which makes it much flatter than the spinnaker.
Windseeker : This sail is small, and it’s designed to guide light air onto the lee side of the mainsail. Moreover, it’s tall and thin and ensures a smoother flow of air.

Sail and Mast Configurations

Now that you got an idea of the different types of sails on a sailboat, it would also be an advantage to know how these types of sails are related to the configuration of a sailboat’s mast. There are numerous combinations when it comes to sails and mast configurations, let’s see some of them!

Cat: A cat is similar to a dinghy and has one mast and one sail. The mast is located at the bow of the sailboat.
Sloop: The sloop has the classic single mast and a double sail setup. The headsail can be different kinds of jibs, is connected with the forestay on the mast, and runs all the way up to the mast.
Fractional Rig Sloop: A fractional rig sloop is different from the sloop because its forestay doesn’t reach the top of the mast. Its headsail is restricted to a fractional amount of space and this means that less wind can be captured, therefore the speed of the sailboat is reduced.
Cutter: Having two forestays on the mast and cutters that are able to house two headsails this setup allows easy cruising because it offers a wide combination of points of sail for different strengths of wind.
Ketch: Just like a sloop the ketch has a mast that enables the mainsail and headsail to a full range forestay. However, it also has a smaller mast between the mainmast and the stern of the sailboat.
Schooner: A schooner is when a sailboat has two or more masts but it has a couple of sails to manage. A schooner’s aft mast is taller than the forward mast and sometimes a schooner can have up to six masts.

Names of Sails on a Sailboat – Summary

So, how many types of sails are there? In general, sailboats have one mainsail and one headsail. The rigging also affects the types of sails you can use. As we’ve explained before, the mainsail is a fore-and-aft Bermuda rig. Then, for a headsail, we use a jib or genoa. Most experienced sailors use extra sails to ensure better performance for their sailboat. For example, the spinnaker (a common downwind sail), the gennaker, the code zero (for upwind use), and the storm sail. Keep in mind that every sail has its own use and performance. Want to go downwind fast? Use a spinnaker. Don’t just raise any sail you think suits you best and go for it! It’s of great importance to understand the functionality, use, and performance of each sail.

World's Largest Sail-Powered Cargo Ship Has Embarked Maiden Atlantic Crossing

Come Sail Away

Earlier this month, a massive sailing cargo ship took off from the French port city Le Havre to make the 3,662 nautical-mile journey across the Atlantic to New York.

The vessel, dubbed Anemos, is carrying a whopping 1,000 tons worth of cargo, blazing the path for a much greener future for the international shipping industry.

The shipping industry is heavily dependent on burning oil, and accounts for roughly three percent of global emissions . By relying partially or entirely on the wind instead of crude oil or diesel, French shipbuilder TOWT is hoping future cargo ships could greatly cut their emissions.

Anemos is the largest sailing cargo ship ever made, measuring 265 long, 49 wide, and 206 feet tall.

According to the company, its sailing cargo ships have a carbon footprint that's just one-tenth of that of a conventional container ship.

"For centuries we knew wind was abundant [over] the deep sea, and we had the pilot charts," TOWT CEO Guillaume Le Grand told New Scientist . "But now, thanks to satellite communication and routing technology, wind is also predictable, which makes it a reliable source of propulsion."

Where the Wind Blows

The unique shipping vessel doesn't rely on human sailors to adjust its sails. A sophisticated system of pulleys, actuators and sensors takes care of the rigging.

It only produces less than 2 grams of carbon emissions per ton of cargo per kilometer, New Scientist reports, while a regular container ship releases over 20 grams.

It's not exactly a racing vessel when relying on wind power, though. Depending on wind conditions, Anemos can reach speeds of over 12 mph, and can also fall back on backup diesel-electric engines in a pinch.

TOWT is hoping to build a fleet of at least eight ships, which could transport a combined 200,000 tons of goods a year to places like Colombia, Martinique, Guadeloupe, and Brazil , which are important coffee and chocolate producers.

Anemos left Le Havre on August 20, and is expected to reach New York by September 3. Fittingly, it's carrying cognac and champagne, which should make for a memorable celebration upon its arrival.

Gary's sexual misconduct scandal has permanently tarnished Below Deck Sailing Yacht.
Bravo must remove Gary from future seasons for the show to regain its reputation.
Season 5 may be in danger of cancellation due to Gary's scandal.

Below Deck Sailing Yacht season 5 is highly anticipated, but its fate isn't promising after Gary King 's sexual misconduct scandal was revealed. Captain Glenn Shephard leads the cast of the exciting spin-off aboard the Parsifal III, with Gary, Colin Macrae, and Daisy Kelliher's love triangle as the pinnacle of season 4's drama. However, after Gary's sexual misconduct allegations were revealed and later brushed under the rug by Bravo producers, the popular franchise staple could be in danger. Will Below Deck Sailing Yacht season 5 return?

During Below Deck Sailing Yacht filming in the summer of 2022, makeup artist Samantha Suarez escorted cast members back and forth for confessional interviews, including Gary. After a talking head in which Gary was visibly intoxicated, Samantha walked him back to his quarters, at which time Gary prevented her from leaving, even grabbing her from behind. While Bravo issued a statement, the allegations were barely addressed, and Gary still allegedly filmed Below Deck Sailing Yacht season 5.

Reality TV is more popular than ever. With so many to choose from, here are some of the best reality TV shows to stream or watch right now.

Gary King's Misconduct Scandal Has Put A Permanent Negative Stain On BDSY

Gary needs to go.

Gary's sexual misconduct scandal has put a permanent stain on Below Deck Sailing Yacht . He's openly struggled with professionalism and alcohol on the show for years. Additionally, this isn't the first time alcohol has gotten Gary in trouble with sexual harassment. While Daisy came to his defense, his love triangle with Daisy and Colin was also problematic, with Gary becoming distracted by the Below Deck drama. By casting Gary in Below Deck Sailing Yacht season 5, Bravo indicated that sexual misconduct wasn't taken seriously by the network .

Below Deck Sailing Yacht Season 5 Needs To Bring It For Bravo To Order Another Season

The series is in trouble.

Below Deck Sailing Yacht season 5 has allegedly already been filmed, with rumors swirling that Gary's scandal has halted its release. Given his prominence in the series, it would be difficult to edit Gary out of the show or even reduce his role. Therefore, it would be better for Bravo to scrap the current season entirely and film a new charter season for Below Deck Sailing Yacht season 5 .

It's the responsibility of Bravo producers to ensure the safety of the cast and crew during filming, and Samantha wasn't adequately protected from Gary's advances.

The cast and crew would need to bring it to revitalize the spin-off, or it's going to get canceled. Below Deck , Below Deck Mediterranean , and Below Deck Down Under are successful enough to continue without Below Deck Sailing Yacht . The popular cast members could go to another Below Deck series.

What Can Below Deck Sailing Yacht Producers Do To Fix The Show's Reputation?

They need to get rid of gary.

Below Deck Sailing Yacht is a sinking ship , but not all hope is lost. Bravo producers have already shown their understanding of the seriousness of Gary's sexual misconduct by disinviting him to BravoCon in 2023. However, they need to further distance themselves from Gary and fire him from future seasons. If it's impossible to decrease his presence in Below Deck Sailing Yacht season 5, the season needs to be scrapped. Only then can Below Deck Sailing Yacht return in good faith and conscience for another installment.

Below Deck Sailing Yacht is available to stream on Peacock.

Sailing yachts like Mike Lynch's are 'unsinkable bodies', CEO of boat manufacturing firm says

Bayesian superyacht which sank off Italy is an "unsinkable" vessel, Giovanni Costantino, CEO of The Italian Sea Group, said.

By Ashna Hurynag, news correspondent and Eleonora Chiarella, producer

Sunday 25 August 2024 08:48, UK

Vessels like Mike Lynch's stricken superyacht are "unsinkable", according to the chief executive of the firm which makes and sells them.

Giovanni Costantino, CEO of The Italian Sea Group, told Sky News there are no flaws with the design and construction of the Bayesian superyacht which capsized in a storm off the coast of Porticello, Sicily, on Monday.

Five bodies were found by divers on Wednesday - taking the number of confirmed dead to six.

The Italian Sea Group also owns the firm that built British tech tycoon Mr Lynch's Bayesian, and Mr Costantino said the vessels "are the safest in the most absolute sense".

News of the sinking left CEO of The Italian Sea Group Giovanni Costantino in ‘sadness on the one hand and disbelief on the other’.

"Being the manufacturer of Perini [boats], I know very well how the boats have always been designed and built," he said.

"And as Perini is a sailing ship... sailing ships are renowned to be the safest ever."

He said their structure and keel made them "unsinkable bodies".

Mr Costantino said news of the sinking "put me in a state of sadness on one side and of disbelief on the other".

"This incident sounds like an unbelievable story, both technically and as a fact," he said.

It is understood Italian prosecutors investigating the incident are continuing to hold interviews with the survivors.

On Tuesday they questioned the captain for more than two hours to help reconstruct what happened and provide useful technical details.

Four British inspectors are also in Porticello and have begun a preliminary assessment of events.

It is understood they will look at all relevant aspects of the incident, including the design, stability, and operation of the vessel. They will also examine the effects of the weather conditions experienced.

Twenty-two people were on board the vessel, 15 of whom were rescued - including Briton Charlotte Golunski and her one-year-old daughter Sofia.

Divers will resume efforts on Thursday morning to bring ashore a body they found earlier. One more person remains missing.

660 pounds of cocaine seized by feds from boat sailing near Puerto Rico

August 30, 2024 / 9:11 AM EDT / CBS/AP

Federal agents seized $6 million worth of cocaine and arrested two men from the Dominican Republic in waters south of Puerto Rico, officials said Thursday.

More than 660 pounds 300 kilograms of cocaine were found aboard a boat traveling south of the U.S. territory on Wednesday, according to U.S. Customs and Border Protection.

It is the latest multimillion-dollar drug seizure this year in waters surrounding Puerto Rico. In July, federal agents seized $4.6 million worth of cocaine west of the island. Two U.S. citizens were arrested.

Puerto Rico is considered a transit point for drugs being smuggled to the U.S. mainland and other countries.

In June, the U.S. Coast Guard said it offloaded more than 4,800 pounds of cocaine worth over $63 million at a port in Florida after officials said Coast Guard officers fired at and sank a speedboat suspected of smuggling drugs in the Caribbean Sea.

About a week before that, a separate Coast Guard crew offloaded $468 million worth of cocaine in San Diego . That haul was the result of eight separate operations off the coasts of Mexico and Central and South America.  

Bricks of cocaine have also been washing up on Florida beaches in recent months -- at least five times since the beginning of the year.

Introduction

Lateen Sail Is Fun But Here’s What You Need To Know: A blog about lateen sails and why they are awesome.

A lateen or latin sail is a triangular sail set on a long yard mounted at an angle on the mast, running in a fore-and-aft direction.

The lateen evolved out of the square rigged tanja sail, used by the Arabs and Greeks to reach East Africa and the Indian Ocean.

The modern Arab dhow is still rigged with one or two lateens, while most other boats use a fore and aft sloop rig, sometimes with a jib.

Lateens were also used on Roman ships to round the Iberian peninsula.

From the beginning of the 12th century, as trade flourished between Egypt and India, the lateen gradually came into use in the Mediterranean.

The Chinese junks have a hybrid rigging – with a forward-facing boom-rigged mainmast with one or more lugsails, and one or more lugsails on each side of the mizzen mast.
