98:, neither of which were seen as fully satisfactory by the Swedish Sailing Federation. The committee completed its proposal the following year. It was accepted as the first Square Metre Rule: yachts were to be classed by their sail area which was fixed. In addition, there were minimum requirements for weight and cabin measurements. Four new classes were originally accepted: 22 m, 30 m, 45 m and 55 m. Soon, new classes were to follow: the 38 m class in 1912; 15 m, 75 m, 95 m, 120 m and 150 m classes in 1913; finally in 1915, the 38 m and 45 m classes were combined into a new 40 m class. The new rule became very popular within the Baltic region; between 1907 and 1920, Finnish yards alone built some 600 Square metre rule yachts. During peak years, Skerry cruisers made up 95 percent of the yards' output. They were also exported to other European countries and the United States.

22 m and 30 m. Larger classes are mostly boats built prior to the 1925 rule and generally only found in the Baltic, where they are dutifully cared for by enthusiasts. Although it was never quite as widespread as the
International Rule, the Square Metre rule has a devoted following in many countries. Strongholds of the rule have traditionally been Sweden, Finland and Germany, which also had national Square Metre rule boats, known as

soon came up with very extreme designs which pushed contemporary sailboat technology to its limits. Development was dramatic: for example, whilst early 40 m boats tended to be around 9 to 10 metres long, in 1923 Westin designed a 40 m boat which was 15.2 metres long and had a beam of only

The Square Metre rule was much less restrictive than competing
International Rules. The relatively loose set of rules allowed previously built boats into the new classes if their rigging was modified to comply with the rules. They also gave designers relatively free hand, and top designers like the

As weaknesses of the original rule became apparent, the
Swedish Sailing Federation enacted a number of modifications from 1916 onwards. Construction standards became much more strict and classes had minimum freeboard and maximum lengths defined. The Rule also specified new minimum measurements for

As with many other sailing handicap and construction rules, the Square Metre rule fell in popularity as its weaknesses were discovered. However, in its revised form it has proved to be enduring and new boats following the rule are still built today. The internationally most active classes are the

This development quickly led to diminishing popularity of the Square Metre rule as these extreme hulls were perceived simply as too weak and uncomfortable to ride. 30 m and 40 m classes were accepted to the
