The International Canoe (IC) (also known as the International Ten Square Meter Sailing Canoe) is a powerful and extremely fast single-handed sailing canoe whose rules are governed by the International Canoe Federation.

It is a boat with 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 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 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 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.[1]

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 the RYA Portsmouth Yardstick handicap scheme. The one-design class uses a Portsmouth number of 905.[2] The Asymmetric Canoe has a faster Portsmouth number of 870,[2] making it 3.9% faster.
