''Reliance'' was the 1903 America's Cup defender, the fourth defender from the famous designer Nat Herreshoff, and reportedly the largest gaff-rigged cutter ever built. ''Reliance'' was designed to take full advantage of the Seawanhaka '90-foot' rating rule and was regarded as a "racing freak", suitable only for use in certain conditions. The 1903 America's Cup was the last to be raced according to the Seawanhaka rule. ==Design== Her design took advantage of a loophole in the Seawanhaka '90-foot' rating rule, to produce a racing yacht with long overhangs at each end, so that when heeled over, her waterline length (and therefore her speed) increased dramatically (see image at left). To save weight, she was completely unfinished below deck, with exposed frames. She was the first racing boat to be fitted with winches below decks, in an era when her competitors relied on sheer man-power. Despite this she carried a crew of 64 for racing due to her large sail plan. From the tip of her bowsprit to the end of her boom, ''Reliance'' measured , and the tip of her mast was above the water (the height of a 20-story building).〔 Everything else was to an equally gargantuan scale; her spinnaker pole was long, and her total sail area of was the equivalent of eight 12 meter class yachts.〔 (【引用サイトリンク】title=America's Cup Hall of Fame )〕 ''Reliance'' was built for one purpose: to successfully defend the America's Cup.
