# 15-metre class

the 15mR Ma'oona in 1908

The International Fifteen Metre Class yachts are constructed to the International Rule. A total of twenty 15 metres were built during the ten-year period between 1907 and 1917. Four of them have survived until today.[1] The 15 metre 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 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. The twenty boats that were built, were raced in Spain, France, Britain and Germany. The rule was proposed for competition in the 1908 Olympics but there were no entries.

## 1907 Rule

Tuiga is one of four 15mR survivors

Used from 1907–1920

$15~\mbox{m}=\frac{\textrm{LWL}+B+\frac{1}{3}G+3d+\frac{1}{3}\sqrt{S}-F}{2}$

where

• $\textrm{LWL}$ = Load Waterline Length in m
• $B$ = beam in m
• $G$ = chain girth in m
• $d$ = difference between girth and chain in m
• $S$ = sail area in m²
• $F$ = freeboard in m
