15-metre class

The International Fifteen Metre Class is a construction class, meaning that the boats are not identical but are all designed to meet specific measurements in a formula, in this case the International Rule. In their heyday, Metre classes were the most important group of international yacht racing classes, and they are still actively raced around the world. "Metre" does not refer to the length of the boat, but to her rating; the Length Overall of 15mR boats measuring almost 30 metres (98 ft).

History

The IYRU International Rule was set up in 1907 to replace the YRA 1901 revised Linear Rating Rule. The IYRU 15mR boats would replace the YRA 52-raters and open competition to foreign nations, replacing local or national systems with a unified rating system across Europe. The rule changed several times, but the 15mR boats only raced in the first rule of 1907. Only twenty boats were ever built, and were raced in Spain, France, Britain and Germany. The rule was proposed for competition in the 1908 Olympics but there were no entries.
