5O5 (dinghy))
The International 505 is a one design high-performance two person monohull planing centerboard dinghy.
The genesis of the class began in 1953 with the creation of the 'Coronet' dinghy designed by John Westell. This sailboat competed for the two person performance dinghy classification for the Olympics at the International Yacht Racing Union (IYRU) trials of 1953 held at La Baule, France. In 1954, the Caneton Association of France requested John Westell to make significant changes to the design to suit their needs. This reduced the overall length, weight and reduced the sail area to become the 505, so named for its length of 5.05 meters. The class achieved international status with the IYRU in 1955.

The class is a popular international class and is actively raced in 18 countries around the world. World championships are held every year at rotating by continent locations around the world, and attract in excess of 100 boats on the start line. The 2005 world championships are to be held in August at Warnemünde, Germany.
The design of the boat's hull shape and sailplan are tightly controlled, while the spars, foils and disposition of the rigging is open. This allows the boats to be set up to the needs of the sailor, rather than controls established by the class association, resulting in a high level of adaptability to sailing styles. There are a number of successful sail/layout combinations.
As of 2005, there are 14 known builders throughout the world. Construction materials range from figerglass/polyester to carbon fiber, with just about every conceivable construction material used at one time or another within the class. Modern boats with modern materials are capable of remaining competitive at the international level for ten years or more. As of 2004, nearly 8,900 505s had been built since 1954.
