Tomahawk 25

Tomahawk 25 is a 25 ′ 3 ″ / 7.7 m monohull sailboat designed by Alan F. Hill and built by Marine Construction Ltd. starting in 1970.

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)

Roughly half were delivered with bilge keels. (Draft 3.0’). Fitted with a number of different inboard engines.

Broker's Comments

The Marcon built Tomahawk 25 is a popular fast small cruiser, ideal for both estuary and coastal sailing. This well maintained example is one of the much sought after bilge keel versions. She has had many updates in recent years including a new engine, batteries, new mainsail, and much of her standing rigging replaced including the fitting of an inner forestay. The current owner has also carried out some clever interior modifications, including a custom made fold away navigation table, and a new engine housing that allows easy engine checks and maintenance. Please note the windvane is not included in the sale,

Broker's Comments

The Tomahawk 25 was known to be a good performance yacht that would accommodate the family with a surprising amount of headroom.

She is an attractive and good value small cruiser that performs well, particularly in this fin-keel form. The Tomahawk is fun to sail

Thanks to Dan Walters Franklin Winter founded Tomahawk Boat Co. in Tomahawk, WI, in 1940s and at first the firm made wooden boats, primarily of cedar strip construction but eventually of plywood. Sometime in late 1940s or early 1950s, Winter began experimenting with then-new fiberglass, at first using it to seal wooden boat hulls, and eventually to build entire boats from molds. Winter is considered to be one of the pioneers of what became an explosion of middle-class boating after World War II, thanks to the advent of relatively inexpensive fiberglass boats. US Rubber in Naugatuck, CT, was the source of resin and Fero in Nashville, TN, was the source of fiber for the early glass experiments. When the market fell apart one year and nobody was buying boats, the plant found work in other products. Winter designed a fiberglass golf cart marketed by Harley-Davidson (examples are very rare today and much prized by H-D collectors) and the boat company also made milk storage outer shells for Solar, Papermill hoods, frames for billboards, Hough cabs (driver shells), Santa sleds, stage coaches, and fiberglass signs. One of the non-boat products was saddlebags for H-D motorcycles. Harley bought 51 percent of the company circa 1960*(see time line below) remainder shortly thereafter. H-D marketed Tomahawak fiberglass boats under its name for one year – another scarce collectible – but quickly abandoned the boat business. It still manufactures saddlebags in its "Tomahawk Division." After selling to H-D, Winter founded Lake Tomahawk Boat Co. and continued to manufacture traditional wooden boats until his death in the 1990s. During the heyday of its fiberglass boat business in the 1950s, Tomahawk was one of the country’s leading manufacturers. Evinrude used Tomahawks exclusively in its catalog one year, the U.S. pavilion at the Brussels World's fair had a Tomahawk fishing boat, and Winter’s futuristic racing boat "On Target" (which is still maintained by the local historical society in Tomahawk) was featured in Newsweek on the Today television show during a boat show in New York City. "On Target," with its fighter-plane-like fuselage, was part of Winter’s extensive involvement in boat racing. And Tomahawk advertising brochures of the period almost always used pictures of its boats with Winter’s children at the controls and/or riding.

Tomahawk Association

The Marcon Tomahawk started production in 1970 and

was first shown at the 1971 London Boat Show in 1970. There were around 290 boats built in the following 10 years. The original Tomahawk 25 was built by Marcon Marine as a small fast cruising yacht with five berths in a semi open plan layout. Also by Marcon Marine at this time were the Sabre 27, Rival 32, Halberdier 36 the Marcon 24 and the Marcon 34.

The Tomahawk Owners Association was launched in 1999

In 1996 Alison and David Collinson purchased their Tomahawk Keewaydin (The wind that takes you home) in Topsham Nr Exeter, and after much preparation in 1977 they sailed her to Brixham and Dartmouth then across to Cherbourg, St.Vaast-le-Hougue, and Le Harve, then via the rivers and canals of France to the Mediterranean, then on via Gibraltar to Portugal. On returning home they felt that such a sterling yacht deserved to have a Class Association, so they set about advertising for potential members who might be interested in forming a Class Association. By Spring 1999 they had the names of about 15 interested parties, and with the help of Michael Juer,  past owner of “Warpath”, they arranged an inaugural meeting at the Red Lion in Chieveley on March 27th 1999. About 12 people sat round the table to discuss whether or not to form an Association. The rest is history, Bill Garrod kindly agreed to take the office of Commodore, I offered to be Secretary, and Geoff Hilditch, although not able to be at the meeting, took the office of Treasurer, the
