For the 1930 America’s Cup the Nat Herreshoff "Universal Rule" was adopted and, despite the serious Wall Street crisis of 1929, American bankers chose the J-Class as racing boats, indifferent to the exorbitant costs of building and running hulls measuring 135 to 145 feet (36 m / 40.5 m) and requiring a crew of 35/40. From 1930 to 1937, only three editions of the Cup were raced, and 10 J-Classes were built (only one of these, the British Velsheda, was not designed to race in the America's Cup). With the arrival of the J-Class, the New York competition field is left for Newport R.I. (the NYYC summer headquarters) and the races run in real time: the first to arrive wins.
