The context here is Yachting is it not? Can we have a somewhat less "universal" title? -- Wetman 21:20, 29 August 2005 (UTC)
Is the Length factor the overall length or the waterline length? I'm guessing waterline but I don't know much about boats. Lisiate

The Universal Rule (Universal Rule for Yachts) determined a yacht's eligibility to race in the America's Cup from 1914 to 1937 and for this the J-class was chosen. Boats built according to the rule reached their peak in the large J-class yachts. This Rating Rule is intended to calculate a rating for yachts, which can then be used to calculate its Time Correction Factor (T.C.F.) in order to have disparate yachts racing against each other. Before 1914, the Seawanhaka Rule was used for America's Cup racing, and after 1937 smaller boats were desirable, and so the International Rule gained popularity in the 12-Metre Class and smaller to the detriment of the M-class and smaller and became the standard. The 6, 8 and 12 Meter (Metre)16:05, 16 June 2014 (UTC) Classes and from 1948 on the 5.5-Meter (Metre)16:05, 16 June 2014 (UTC), were the most popular and the 12-Metre was used for the America's Cup until 1987, the last year the America's Cup was sailed in 12-meter yachts. Yacht designer Nathanael Herreshoff devised the rule in 1902 "Herreshoff Rule" and accepted by the New York Yacht Club as the rule-making body for 1903. [4] [5] Herreshoff had designed winning America's Cup yachts which fully exploited the Seawanhaka rule, which was based only on a yacht's upright waterline length and sail area, to create narrow boats with long overhangs. This reached its peak with Reliance, the defender of the 1903 America's Cup, which was described as a "racing freak", suitable only for certain conditions. [6] This prompted Herreshoff to propose a rule which also took into account the displacement of the boat. [7] Mathematically, the Universal Rule formula as introduced in 1903 was: [8] Variables:
The numerator contains a yacht's speed-giving elements, length and sail area, while the retarding quantity of displacement is in the denominator. Also the result will be dimensionally correct; R will be a linear unit of length (such as feet or meters). Sailing craft are thus rated when their rating falls within a certain range. J-Class boats, for example, are any single masted craft with an between 65 and 76 feet (adjusted upward from original to allow British yachts under the International Rule to compete. The listing for single mast boats, namely classes I through S. Skene,1941, indicates this applicable to yachts from around 1930:16:05, 16 June 2014 (UTC)
