Improve sailing performance

With forte’s super durable carbon masts and booms.

Forte masts and booms are manufactured using 4-Axis Continuous Fiber Braided Technology originally developed for military applications requiring “super durability” – the ability to withstand bullet shots and to resist spread of damage.

Why Buy A Forte Carbon Fiber Mast?

Forte also uses proprietary process control computers to strategically place and braid each carbon fiber strand directly onto a precisely engineered mandrel. The finished mast is then consolidated and cured at high temperature.

Save Weight Aloft

A Forte carbon fiber mast weighs about half that of an aluminum mast. Weight savings aloft translates into increased righting moment and reduced pitching moment. In heavier winds, your boat will pitch less in chop. Increased righting moment means you can keep more sail up and/or sail with less crew under any heavier conditions.

Yes a carbon mast can be affordable! Our automated manufacturing process allows us to manufacture carbon spars with less hands-on labor than other manufacturers. This means lower cost for you. Also, with some aluminum extrusions becoming scarce along with the labor to have the extrusion tapered…You may be surprised how affordable a Forte carbon spar can be.

Double Life Expectancy

Carbon fiber masts require less maintenance than aluminum masts; carbon fiber does not corrode, and paint flaking associated with aluminum masts does not occur. And, because softer (i.e., lower modulus) aluminum masts are subject to greater fatigue than carbon fiber masts, a Forte carbon fiber mast has at least double the life expectancy.

Transfer Power Efficiently

Power created by your sails is transferred by your mast to your hull. Softer aluminum masts lose some of this power because of bending, flexing and vibration. Due to greater strength and stiffness, a carbon fiber mast efficiently transfers the power from the wind into forward sailing momentum for greater speed.

Meeting Every Requirement

Forte carbon fiber masts are engineered to meet your exact requirements. Your mast can be built straight or tapered, to your specified weight or stiffness. Localized reinforcements (additional material) are laminated into the spar at areas of high stress and locations of any hardware or holes in the spar wall.

Spars can be ordered as a blank (bare carbon tubing) or a fully finished and painted mast.

We build OEM masts for manufactures such as:

• Classic Boat Shop
• Zim Sailing

Whether Cruising or Racing

You can expect your forte carbon mast to improve your boat’s sailing performance..

what they’re saying

The carbon fiber tubing we use in the Mosquito Air Helicopter has proven to be very reliable and strong. Forte offers a good product at a very reasonable price.

Before and during the 2002/2003 Around Alone race, we broke every type and every brand of sail batten you can imagine. This is one thing about Ocean Planet’s unstayed (freestanding) mast, that it is very tough on battens. However, for the end of the Around Alone and for the Vendee, we are using custom braided S-glass/carbon fiber battens by Forte… Forte battens are incredible, and it is so nice not to have to worry about battens anymore.

Thanks for the awesome new mast for Strummer. It’s made a huge difference; she’s a much better boat, definitely stiffer and faster. We took 2nd (Class IV) in this year’s (2007) Bermuda 1-2. Lots of days in the 25-30 knot range. No problems with the rig at all.

My Forte mast is fantastic. It is light and extremely strong… two gales in the Bay of Biscay and three flying gybes (thanks to autopilot malfunctions) with the spinnaker up, and each time it came through unscathed. ACADIA Once I gybed in 30 knots of wind 2 miles from the finish with a full main and broke one of the running backstays, so no backstays on downwind… no problems.

Strong, light and fairly priced ~ a good value! That’s what our clients tell us about their Forte poles. And we appreciate having a reliable source of spinnaker poles to meet our clients’ expectations.

I would like to thank you, Tony and all the crew at Forte for the great service and excellent product. As you know, we were without a supplier for a mast, spirit and spinnaker pole for the new Rocket, and your company was the only one with a “can do!!”attitude. Right from helping us to pick the correct mandrel, creating the laminate schedule, to helping us construct the first mast, you went beyond the call of duty. We were nervous that the mast would be too stiff, and had lots of “nay sayers”, but when we set the rig up and went for our first sail, it was just what we were looking for!! Keep up the great work!!

BOOMS WITH A STRONG PROFILE

Seldén booms have a wealth of sophisticated features and can be equipped with a variety of reefing systems to suit different boats and the needs of different sailors. The booms can be fitted for traditional slab reefing or Single Line Reef, or be used for furling masts. The boom extrusions are relatively deep in relation to their width, allowing a lighter extrusion with high resistance to vertical bending. This makes them perfect for use with modern, stiff sailcloth and efficient Rodkicker rigid vangs.

WHY YOU NEED A NEW BOOM

The most common upgrade is to a Single Line Boom. Remain in the cockpit and pull one line to reef your sail and you will prevent adventurous maneuvers at the mast. It’s quick, safe, easy to handle and convenient.

It’s full of potentials. A new boom is prepared for Rodkicker, Lazy jack sliders, easy installation of a stack-pack system and boom light that will lighten up your cockpit at night.

MAKE IT HAPPEN – IT’S EASY

To decide what you need, here are a few useful steps:

• Check if your boat is listed here . If it is you will know what size boom we recommend and its part number.
• Find out how stiff your boat is by calculating the Righting Moment (RM) at 30° heel. This is done with our calculator .

Click on technical information below and use the dimensioning table for Masthead rigged boats or Fractional.

• You need to know the RM, the E-measurement and the Y-measurement to make your choice and all those measurements are explained in this area.
• Compare the forward end of the Seldén boom to the dimensions of the boom bracket on your mast. Clevis pin dimensions and width and depth of the forward end.

Or… just ask a Seldén dealer to figure it all out.

LIGHT BOOMS IN CARBON FIBRE

Seldén supply carbon booms that harmonise with its carbon mast range. Carbon booms offer weight savings of up to 35% compared to aluminium. This means that boom weight on a typical 35 ft boat is reduced from 30 kg to just 20 kg.

A lighter boom makes gybing less dramatic, as the boom has less momentum. This has a positive effect on the whole boat, especially with regard to the service life of the mainsheet attachment.

A lighter boom also reduces the tendency of the boat to roll when sailing downwind and it improves the effect of the Rodkickers’ gas spring. The section modulus of a carbon boom is twice as high as that of an aluminium boom with the same weight per meter. A stiff boom makes for improved trim and thus higher boat speed.

Boats that sail IRC, and which are already fitted with a carbon mast, suffer no further rating penalty by up-grading to a carbon boom.

In order to reduce weight, while still providing sheaves for single line reefing, we have made the inboard end fitting as short as possible. The outboard end, which is integrated into the carbon section, is finished with a carbon cover plate.

The mainsheet block is attached using a Dyneema® strop that passes through an aramid tube in the boom. Stainless steel bushings at either end of the tube prevent wear, while local carbon reinforcement provides the extra strength required. Booms with “German” split mainsheet systems have fastening positions for blocks at the inboard end, and two webbing strops to hold up the mainsheet.

The carbon booms feature hand laid local reinforcement in the vang attachment area.

Carbon booms can be supplied ready for conventional slab or single line reefing. Clutches can be integrated into the inboard end if you do not wish to lead the reef lines to the cockpit.

The standard Seldén outhaul system features a Dyneema® outhaul line for leading back to a winch in the cockpit. As an alternative, an internal cascade system with up to 20:1 purchase can be used and operated by hand from the cockpit or by a crew member hiking on the rail.

BOOMS FOR DINGHIES

Seldén dinghy booms have been designed to offer the ultimate in stiffness, weight and functionality. From single-line reefing systems to high-purchase internal outhaul systems, Seldén booms can be equipped with a range of sophisticated features that will make your sailing easier, faster and more convenient. Class rules are closely studied to push performance to the limit. For example, the Olympus boom section optimises the 470 class rules to give the lightest and stiffest boom the class rules allow.

All sections are optimised for high resistance against vertical bending and come with an integral sail track and lower in-boom track for mainsheet and kicking strap attachments.

FINEST CARBON BOOMS

Southern Spars has a full time  team of experienced designers , dedicated to designing booms of all varieties, with integrated RigCalc software at their fingertips. The project specific design of a boom plays a vital role in the performance and usability of a yacht’s sail,  spar  and  rigging  package.

Southern Spars  designs  and produces a range of booms from 11-foot foiling moths up to mega yachts stretching more than 200-feet. They are all  constructed in carbon  from with specially shaped moulds, unlike many manufacturers, who use make do with generic moulds. This makes the booms lighter, with superior aerodynamics and sleeker looks.

BOOMS FOR ALL APPLICATIONS

Park avenue.

Retaining many of the benefits of a Racing Box Boom when sailing, the Park Avenue has the advantage of a wide top wing platform to make flaking sails a breeze. Soft lines make this a truly classic looking boom.

Benefits of the Park Avenue;

• Wide top wing platform
• Performance benefits
• Sail reefing
• Adjustment controls
• Enhanced sail tuning ability

This is Southern’s full noise race boom. It is often deep in section to provide maximum stiffness to weight efficiency and to give added downwind effective sail area. Differing cross sectional shapes are available to suit the yacht’s performance requirements.

Possibility to add outriggers for supporting flaked sails.

Benefits of the Racing Box Boom:

• Excellent strength to weight ratio
• Maximised downwind effective sail area

Similar in application to the traditional Park Avenue Boom, the Veelux Boom offers a much deeper sail flaking cavity to almost completely hide the stowed sail. This gives a cleaner, minimalistic look when at rest.

The shape offers a contemporary look, with strong lines whilst still retaining the classic aerofoil curves along its length. The result is an ultra-clean boom package with deceptively large volume for sail storage.

Benefits of the Veelux Boom;

• Deep sail flaking cavity
• Clean, contemporary aesthetics
• Classic aerofoil curves

Our Truss Wing Boom offers a high performance alternative to the Park Avenue design. The Truss Wing Boom is, in essence, a racing box boom, with secondary bonded lightweight truss wings. It is lightweight and sports clean lines, ideal for a cruiser/racer.

Benefits of the Wing Boom;

• Cost effective
• Lightweight
• Easy sail stacking

Southern Spars´ in boom furling technology has changed the game for superyachts with furling main sails. We have a range of drive systems to suit your yacht and the desired specification of your boom, including electric and hydraulic powered furling options. Customise your boom with extras; custom paint finish, flush-mounted LED lights, mainsheet preventer, internal mainsheet.

Benefits of the Furling Boom;

• SouthernFurl’s design allows full-length sail battens, giving your sail a better flying shape and decreasing flogging, therefore increasing the lifespan of your sail.
• Carbon fibre construction is strong and stiff.
• Quick and simple to retrofit.
• Open front means minimal sail distortion which increases the tolerance of an imperfect furl.

The Pauger Carbon Vang is a lightweight, stylish solution for any yacht type. A 5:1 (7:1 in larger models) internal purchase system keeps the design clean, while the outer surface has a clear coat varnish.

Pauger Carbon Vangs

A Pauger Carbon Vang is a vital piece of sailing equipment used to control the tension and position of a sailboat’s boom. Constructed from carbon fiber, these boom-vangs offer several advantages over traditional materials, making them a preferred choice for modern sailors, especially in competitive racing and high-performance sailing.

Key Features and Benefits:

• Material : Carbon fiber is renowned for its exceptional strength-to-weight ratio. This makes carbon boom-vangs much lighter than those made from aluminum or stainless steel, which helps reduce the overall weight of the rigging and improve the sailboat’s performance.
• Strength : Despite their lightweight nature, carbon boom-vangs are incredibly strong and capable of withstanding the high loads and stresses encountered while sailing.
• Rigidity : The rigidity of carbon fiber ensures that the boom-vang maintains its shape and does not flex under load, providing precise control over the boom’s position.
• Efficiency : With reduced weight aloft, the sailboat can respond more quickly to changes in sail trim and wind conditions, enhancing overall sailing efficiency and speed.
• Durability : Carbon fiber is highly resistant to corrosion and degradation from exposure to saltwater, UV radiation, and other harsh marine conditions. This leads to a longer lifespan and reduced maintenance compared to metal vangs.
• Installation : The lightweight nature of carbon vangs makes them easier to handle and install, reducing the physical effort required by the crew.
• Adjustability : Modern carbon vangs often come with advanced adjustment mechanisms, allowing sailors to fine-tune the tension and angle of the boom with precision.
• Modern Look : Carbon fiber has a sleek, modern appearance that adds to the aesthetic appeal of the sailboat, often preferred by sailors who value both performance and style.
