Class History

The Finn legacy began with the Finnish Yachting Association's 1948 search for a new dinghy. Rickard Sarby's winning design, based on a Nordic double-ended sailing canoe, quickly became the Olympic singlehanded men's dinghy for the 1952 Games in Helsinki and has appeared in every Summer Games since. With an unstayed mast and 10.6 sq. meters (115 sq. ft) of sail area, the physically demanding 4.5 m (14'9")Finn is closely associated with many renowned sailors. John Bertrand and Russell Coutts, the only two helmsmen to beat an American Defender in the America's Cup, as well as the legendary yachtsman Paul Elvstrom, are all Olympic medalists in the class. The Finn is also part of Harken's history; Vanguard, the boatbuilding company that the Harken brothers founded alongside their hardware business, designed a hull in 1975 that dominated the international Finn circuit until the mid-1990s. finn-sailplan.gif

Hiking Strap Adjustment

Sailors can fine-tune the angle of the hiking straps out on the water for different sized waves, wind speeds, and body types. Strap tension can be adjusted to suit a range of sailor heights. Shockcords pull the straps inboard and out of the way when not in use.

Centerboard System

Partially raising the centerboard downwind reduces drag and lessens the side load. The double-ended 2:1 system also allows racers to quickly clear the centerboard of seaweed and debris.

Mainsheet Traveler

The traveler system uses all Small Boat gear and bearing systems. In light air, the 2:1 traveler adjusts the sheeting angle and the twist of the sail.

The 3:1 mainsheet system is tensioned via the swivel base in the cockpit and bends the mast. When the bend exceeds the sail's luff curve, the mast inverts and flattens the sail. Less bend increases the sail's draft. The Finn class does not restrict pumping in heavy winds, and the deadend on the boom allows a powerful 1:1 downwind.
