Finn One Design - Rigging and Parts

Finn: Heavyweight Olympic Dinghy
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. The Finn is now the longest standing of any Olympic dinghy class, currently filling the slot for the Heavyweight Dinghy. Historically, the Finn as seen sailing legend such as Paul Elvstrom, John Bertrand, and Russel Coutts, and Ben Ainslie take the helm.

The Finn is the most physically and mentally demanding singlehander in the world. 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. It breeds exceptional, all-round sailors by testing all aspects of racing. The hull is almost exactly the same (albeit with optimised GRP construction instead of wood), with tight controls still in place to keep the boat strictly one design. Modern technology such as carbon fiber masts and kevlar sails mean the Finn today is faster and more powerful than ever.

The cult of the International Finn Monotype may seem strange to some people, but to true devotees, there is nothing else remotely like it. The Finn offers the most purely athletic form of yacht racing and is, therefore, the most fundamentally competitive. The Finn offers the rewarding opportunity of doing a difficult thing well. There will always be those who aspire to be the master of a Finn.

Mainsheet System

Finn Mainsheet System
The 3:1 Finn mainsheet system is trimmed from the swivel base in the cockpit, creating significant mast bend. 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 mainsheet to induce surfing downwind.


Centerboard Control

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

Hiking Strap Control

Finn 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 in the Finn can be adjusted to suit a range of sailor heights. Shockcords pull the Finn hiking straps inboard and out of the way when not in use.




Finn Mainsheet Traveler System
The Finn 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 for maximum power.
