60822    The sizes of the competing yachts have changed along with America's Cup history.

60823    They can be roughly divided into 5 eras.

60824    In 1851 the victorious America was a new two-masted wooden schooner 30 meters in length overall.

60825    The two-mast style was popular through the third America's Cup in 1876, but from the fourth competition a single mast style came to dominate.

60826    Before long, steel and copper replaced wood in yacht construction, and from the eighth America's Cup the era of large yachts 36 - 42 meters in length overall commenced.

60827    Beginning in 1930 with the 14th America's Cup was the era of J-Class boats.

60828    The overall length of the yachts did not change from until then, but with each competition the efficiency of the sails improved, and this could be said to be the beginning of the modern America's Cup era.

60829    From the 17th America's Cup, competitions with regulated 12 meter-class yachts began.

60830    The yachts became smaller, with an overall length of 20 meters.

60831    The capacity is eleven people.

60832    Research further advanced, with each syndicate pursuing speed as opposed to endurance, and dramas like Australia's first victory and Dennis Conner's recapture of the Cup unfolded.

60833    Then, at the previous America's Cup in 1992, the era of the current America's Cup-Class yachts began.
