The winner
For the 1930 edition, the syndicates decided to adopt the "J Class" whose rating is fixed. For the first time in the history of the Cup, competitors no longer raced in corrected time, but in real time. The first to cross the finish line was declared the winner! The J Class were defined according to the Universal Rule, a rule published by American architect Nathanael Herreshoff in 1903. The heavy gaff rig was abandoned in favor of a Bermuda rig.
The looser
With each regatta, Shamrock 5 is slower. Its mainsail halyard breaks during the third race.
