The International Canoe ( IC ) (also known as the International Ten Square Meter Sailing Canoe ) is a single-handed sailing canoe whose rules are governed by the International Canoe Federation .
8-439: The boat has a narrow bow entry and a planing hull, carrying a mainsail , and a jib (sometimes self tacking). Stability is achieved with a sliding seat on which the single crew member sits, effectively controlling the boat from 'outside'. International Canoes are raced in three divisions. The main body of the class competes to a development (or "box") rule, allowing significant variation in design between different boats within
16-414: A four-sided gaff rigged mainsail, sometimes setting a gaff topsail above it. Whereas once the mainsail was typically the largest sail, today the mainsail may be smaller than the jib or genoa; Prout catamarans typically have a mainmast stepped further aft than in a standard sloop, so that the mainsail is much smaller than the foresail. The modern Bermuda rig uses a triangular mainsail aft of
24-409: A highly developed and efficient sail plan, and the powerful righting moment afforded by the (single) crew positioned well away from the hull centerline provides possibly the most exhilarating and technically challenging sailing experience available in a mono-hulled craft. The origins of the class can be traced back to the 1860s, and International competition with craft that are recognisably ancestors of
32-481: The RYA Portsmouth Yardstick handicap scheme. The one-design class uses a Portsmouth number of 905. The Asymmetric Canoe has a faster Portsmouth number of 870, making it 3.9% faster.

40-689: The current boats started in 1884. The Class still competes for the New York Canoe Club Challenge Trophy, which was established in 1885 and is believed to be the oldest international sailing trophy after the America's Cup . The class is most popular in Australia, the US and Northern Europe, especially Germany, Sweden and the UK. International Canoes can compete against other classes in a mixed fleet by use of
48-411: The mainsail to project farther away from the mast. However, there is some cost associated with the battens themselves, "batten pockets" need to be sewn into the sail, and "batten cars" may be needed to allow the sail to be raised and lowered. Before Nathanael Greene Herreshoff 's invention of sail tracks and slides in the 1880s, mainsails were limited in height. Traditional mainsails were held against
56-422: The mast, closely coordinated with a jib for sailing upwind. A large overlapping jib or genoa is often larger than the mainsail. In downwind conditions (with the wind behind the boat) a spinnaker replaces the jib. Some mainsails are "full-batten" mainsails, meaning the batten extends all the way from the mast to the leach of a sail. A partial batten extends from the leech partway to the mast. Battens enable
64-470: The rule framework. Within that rule there is a "One Design" subclass which covers boats built to a one design rule in operation between 1971 and 2007, all of which have the same hull shape and are subject to an 83 kg minimum weight limit. The third division, known as the AC (Asymmetric Canoe), uses the 83 kg one design hull and carries an asymmetrical spinnaker . The combination of an easily driven hull with
