Summary Analysis of the Design Ratios for the Challenger 35

1. A Sail Area/Displacement Ratio of just 11.5 suggests that the Challenger 35 will need a stiff breeze to get her going. In light conditions, unless you've got plenty of time on your hands, motor-sailing may be the way to go.

2. A Ballast/Displacement Ratio of 34.1 means that a long-keel sailboat like the Challenger 35, is likely to benefit from being reefed early to keep her sailing upright in a moderate breeze.

3. A Displacement/Length Ratio of 376, tells us the Challenger 35 is firmly in the ultra-heavy displacement category. Load her up as much as you like and her performance will be hardly affected, not that it was ever startling. Few if any sailboats are built to this displacement category these days - but they remain popular with some long-distance sailors.

4. Ted Brewer's Comfort Ratio of 35.1 suggests that crew comfort of a Challenger 35 in a seaway is similar to what you would associate with the motion of a moderate bluewater cruising boat - a predictable and acceptable motion for most seasoned sailors.

5. The Capsize Screening Formula (CSF) of 1.7 indicates that a Challenger 35 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0. 

Cruisers' Questions about this Sailboat...

What is the difference between the Challenger 35 and the Warrior 35?

The Challenger 35 and the Warrior 35 are two of the three 35-foot designs by Angus Primrose for Trident Marine. They share the same hull moulding, but have different deck mouldings and interiors.

The main difference between them is that the Challenger 35 is an aft-cockpit cruiser, while the Warrior 35 is a centre-cockpit cruiser. This affects the layout and the appearance of the boats.

The Challenger 35 has a spacious and bright interior with a good galley and heads amidships. It has seven berths, but the quarter double is more a large single and the saloon is really only for two people. It has a very traditional angular coachroof and a large cockpit with a tiller steering.

The Warrior 35 has a more compact interior with a smaller galley and heads forward. It has six berths, including an aft cabin with a double berth accessible from the cockpit. It has a very distinctive rounded coachroof and a smaller cockpit with a wheel steering. It also has more headroom and storage space than the Challenger 35.

Both boats have a long keel, a masthead sloop rig, and a modest sail area. They are both heavy displacement cruisers that excel in heavy weather and provide predictable, undemanding, but also unexciting, sailing in less demanding conditions. They are both popular with long-distance sailors who value comfort and safety over speed and performance.

What is the third 35-foot design by Angus Primrose for Trident Marine?

The third 35-foot design by Angus Primrose for Trident Marine is the Voyager 35. It is a pilothouse version of the same hull as the Challenger 35 and the Warrior 35.

The Voyager 35 has a large deck saloon with panoramic windows and a steering station. It has a forward cabin with a V-berth, a quarter berth aft, and two settee berths in the saloon. It has a galley and a heads compartment amidships. It has a masthead sloop rig and a long keel.

The Voyager 35 is a rare and sought-after model that offers good visibility, comfort, and protection from the elements. It is suitable for coastal or offshore cruising.

What does a secondhand Voyager 35 sell for?

The price range of the Voyager 35 sailboat depends on the condition, age, equipment, and location of the boat. However, based on some online listings, it seems that the average price is between £25,000 to £45,000.

Of course, this is only a rough estimate and the actual price may vary depending on the market demand, the seller's expectations, and the buyer's negotiation skills. It is always advisable to inspect the boat carefully and compare it with similar models before making an offer.

How many people can sleep on board a Voyager 35?

According to the information I found on the web, a Voyager 35 sailboat can sleep up to six people on board. It has a forward cabin with a V-berth, a quarter berth aft, and two settee berths in the saloon.

However, some owners may have modified the interior layout or added extra berths to suit their preferences. Therefore, the actual number of berths may vary depending on the specific boat.

The above answers were drafted by sailboat-cruising.com using GPT-4 (OpenAI’s large-scale language-generation model) as a research assistant to develop source material; to the best of our knowledge,  we believe them to be accurate.

Challenger 38 (Alden)

Challenger 38 (Alden) is a 38 ′ 5 ″ / 11.7 m monohull sailboat designed by John G. Alden and built by LeComte Yachts, Molich Shipyard, Halmatic Ltd., and Hodgdon Bros. between 1960 and 1965.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

Alden design #949. The Fiberglass hulls were molded by Halmatic Ltd. in the UK and finished with wood decks, usually covered with teak, mahogany cabin trunk and trim, by a number of other yards.

Review of Challenger 15

Basic specs..

The hull is made of fibreglass. Generally, a hull made of fibreglass requires only a minimum of maintenance during the sailing season. And outside the sailing season, just bottom cleaning and perhaps anti-fouling painting once a year - a few hours of work, that's all.

The boat equipped with a fractional rig. A fractional rig has smaller headsails which make tacking easier, which is an advantage for cruisers and racers, of course. The downside is that having the wind from behind often requires a genaker or a spinnaker for optimal speed.

CentreBoard

The Challenger 15 is equipped with a centreboard keel. A centreboard keel is a pivoting lifting keel, allowing to sail both coastal and inland waters.

The boat can sail close to the beach as the draft is just 0.18 - 0.28 meter (0.59 - 0.89 ft) dependent of the load. See immersion rate below.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Challenger 15 is about 48 kg/cm, alternatively 269 lbs/inch. Meaning: if you load 48 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 269 lbs cargo on the boat it will sink 1 inch.

Boat Test: 2024 Stingray 23 OSX

• By John Tiger
• September 1, 2024

It’s no longer common for boatbuilders to offer a fast single-engine outboard sportboat, let alone one available as both a bowrider and a ­cuddy cabin. Kudos to Stingray and its 23 OSX/OSC models,  which deliver a rippin’ fun ride up to a two-way average tested top speed of 68 mph. 

I went out solo and saw 71 on the GPS. I believe that some propeller and jack-plate tweaking might net 75. The  5.4 seconds time to 30 mph is on par with most ­­high-performance hulls. With a ­­­56-gallon fuel tank and 5 mpg at 38 mph, you can run all ­weekend.

Stingray’s patented “Z-Plane” hull adds speed and stability, and is easy to drive. According to design engineer Drew Gantt, the design is optimized for today’s heavier outboard engines. The entire boat is CAD-designed. A composite hull and deck means there’s no wood to rot. The transom is foam-cored and ­infused with resin. Everything is bonded, not just bedded. Warranty is lifetime on the hull and one year on all else. 

Interior and Accessories

In the bow, two wide lounges face forward. The seating is plush and detailed, in a white-and-deep-gray ­vinyl combo that looks crisp. Folding armrests, stainless-­steel grab rails, and cup holders are plentiful. Between the bow seats, I noted a built-in cooler and a very cool anchor locker with a convenient slide-out anchor holder.

At the helm, everything but the Garmin 743 display is standard, including digital switching and Yamaha ­digital engine monitor, Yamaha ­electric power-assist steering, and a Fusion sound system with six speakers. The cockpit is self-bailing—a huge safety and convenience advantage. The deep, plush bucket seats provided stability and ­security at higher speeds. Just ­behind, two longitudinal lounge seats blend into and around a ­full-width stern bench seat.

Under the stern seat, there’s quick access to the battery switch, dual batteries and bilge.  Finished overboard-draining storage lives underneath both stern seats, and a huge, gelcoated compartment stows bulk items such as safety gear and water toys. A wide swim platform offers a built-in cooler and a boarding ladder under a hatch. 

It’s so refreshing to see “fast ’glass” again.

How We Tested

• Engine: Yamaha F300 outboard
• Drive/Prop: Outboard/Yamaha Pro Series 14 1/2″ x 23″ 3-blade stainless steel
• Gear Ratio: 1.75:1 Fuel Load: 45 gal. Crew Weight: 450 lb.

High Points

• A super-innovative roto-molded anchor-storage rack slides out and ­captures the anchor so that it doesn’t scratch up the locker and make a mess.
• Hinged seat cushions stay in the up position, giving you storage access with no need to hold the seat up.
• Z-Plane hull design never fails to impress.
• The only charge ports are at the helm.
• Some might wish for an amp to power the speakers. Stingray leaves that to the buyer, theorizing that those wanting an upgraded sound system usually want their own choices.

Toughest Competitor

True high-performance outboard ­bowriders are few and far between. Checkmate’s 2400 BRX ($135,000 with a Mercury Racing R300) compares closely to Stingray’s 23 OSX. The Checkmate measures 24 feet by 8 feet, 3 inches, weighs 2,200 pounds (boat only), holds 60 gallons of fuel, and sports 22 degrees of transom deadrise. During my recent test, it hit 67 mph.

Grand Menshikov Palace

Menshikov began to build his residence here in 1713, at about the same time as Peter began work on his own estate at Peterhof. Menshikov seemed intent on outdoing his master in terms of scale and grandeur, and commissioned architects Giovanni Mario Fontana and Gottfried Schadel, who were already building the Menshikov Palace in St. Petersburg, to design his seaside palace. After over a decade of work, which eventually bankrupted Menshikov, the palace was completed.

Facing the sea, with a two-level terrace in front of it, this charming yellow and white building consists of a concave central block with two single-storey galleries leading to prominent octagonal pavilions, one of which houses the palace chapel. On the south side of the building, two large ancillary wings, the Kitchen Wing and the Ladies' Wing, run from the pavilions perpendicular to the central block.

Menshikov had little time to enjoy his new palace before he was arrested and exiled in 1727. The estate at Oranienbaum was passed to the state, and Menshikov's palace became a naval hospital. In 1743, the estate was presented by Empress Elizabeth to her nephew, the future Peter III, who commissioned Francesco Bartolomeo Rastrelli, the greatest late baroque architect working in Russia, to renovate the palace. Rastrelli left the exterior of the palace almost untouched, but created sumptuous interiors that have, sadly, long since been destroyed. At this time, the western pavilion became known as the Japanese Pavilion, thanks to the collection of Japanese and Chinese ceramics it housed.

The palace was altered again in 1762 by Antonio Rinaldi, who added a granite staircase and semi-circular balcony to the northern terraces and redecorated many of the interiors. After serving as a Naval Cadet College from the end of the 18 th century, the palace was used as a residence by both Alexander I and his brother Mikhail. During the 19 th century, several famous architects, including Luigi Ruska, Carlo Rossi, and Vasiliy Satsov, reworked the interiors of the palace.

Today, while the Grand Menshikov Palace is still extremely impressive from the outside, its interiors are in a parlous state, and major renovation work still needs to be done to prevent parts of the building collapsing. For visitors, there is little to see except a collection of portraits of the various owners of Oranienbaum.

An Insider’s Viewpoint

“This is our second charter with Waypoints and we could not be more satisfied. Availability and pricing were clear, communication was prompt, and the staff was knowledgeable and nice. The Vinoy Marina is very convenient to a couple of airports so the crew had no problem coming in from all over the country. We think Waypoints is the best charter company available and already have another trip booked for January in St. Thomas!” Jim K.

“The entire team from the Waypoint dock manager, office staff, and dock hands as well as mechanics went above and beyond to make us have a great experience. Sailing Sereia changed me… it was such an incredible trip . With tears in my eyes, I left the boat and I have been counting the days until I can go back and sail her again. We loved all the crew we came in contact with – thank you again!” Constance M.

“We had a great experience with Waypoints Florida Yacht Charters! We spent four days in Florida on Leap of Faith and had a great time. It was our first sailing adventure. We explored Tampa Bay, Anna Maria, Egmont, Bradenton and Palma Sola. It was a great escape! “ Mark L.
