Specifications of the J-Class
< The Universal Rule was established in 1903 by Nathanael Herreshoff and the NYYC to normalise the sailing sport at every size of boat. The J-Class was first developed in 1929 from the Universal Rule and rates boats with the following criteria:
 * rating: $$65<\frac{0.18\cdot\textbf{L}\cdot\sqrt{Sail~Area}}{\sqrt[3]{Displacement}}\le76$$where:
 * $$\textbf{L}=L.W.L.+.5(q.b.l.-\frac{100-\sqrt{L.W.L.}}{100}\cdot L.W.L.)$$
 * $$L.W.L.$$ is the Load Waterline Length in feet
 * $$q.b.l.$$ is the quarter-beam length in feet
 * $$Sail~Area$$ is measured in square feet
 * $$Displacement$$ is measured in cubic feet
 * 76 ft $$\le L.W.L.<$$ 88 ft
 * maximum draught: 15 ft
 * minimum mast weight: unrestricted in 1930; 5500 lb in 1934; 6400 lb for the whole rig in 1937
 * standards: Lloyds' A1 scantling rules
 * build: aluminium hull forbidden in the 1930s, authorised today
 * design: 1930s (replicas are only rated to the J-Class provided their design dates back to the 1930s)
 * racing: elapsed time (1930s), Velocity Prediction Program ratings (today)
