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: $65<{\frac {0.18\cdot {\textbf {L}}\cdot {\sqrt {Sail~Area}}}{\sqrt[{3}]{Displacement}}}\leq 76$
  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 (23.16 m) $\leq L.W.L.<$ 88 ft (26.82 m)
• maximum draught: 15 ft (4.57 m)
• minimum mast weight: unrestricted in 1930; 5,500 lb (2,500 kg) in 1934; 6,400 lb (2,900 kg) 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)
