The America's Cup, informally known as the Auld Mug, is a trophy awarded in the sport of sailing. It is the oldest international competition still operating in any sport. America's Cup match races are held between two sailing yachts: one from the yacht club that currently holds the trophy and the other from the yacht club that is challenging for the cup. Matches are held several years apart on dates agreed between the defender and the challenger. There is no fixed schedule, but the races have generally been held every three to four years. The most recent America's Cup match took place in March 2021.
Nathanael Greene Herreshoff was an American naval architect, mechanical engineer, and yacht design innovator. He produced a succession of undefeated America's Cup defenders between 1893 and 1920.
The J Class of racing yachts were built to the specifications of Nathanael Herreshoff's Universal Rule. The J Class is considered the apex of the era when the Universal Rule determined eligibility in the America's Cup.
The Universal Rule determined a yacht's eligibility to race in the America's Cup from 1914 to 1937 and for this the J-class was chosen. Boats built according to the rule reached their peak in the large J-class yachts. This Rating Rule is intended to calculate a rating for yachts, which can then be used to calculate its Time Correction Factor (T.C.F.) in order to have disparate yachts racing against each other. The first boat said to be built under the universal rule was Herreshoff's Doris built in 1905.
Reliance was the 1903 America's Cup defender designed by Nat Herreshoff.
Defender was the victorious United States defender of the tenth America's Cup in 1895 against challenger Valkyrie III. Defender was designed by Nathanael Greene Herreshoff and built by the Herreshoff Manufacturing Company in 1895. It was Herreshoff's second victorious America's Cup defender design.
Vigilant was the victorious United States defender of the eighth America's Cup in 1893 against British challenger Valkyrie II. Vigilant was designed by Nathanael Greene Herreshoff and built in 1893 by the Herreshoff Manufacturing Company of Bristol, Rhode Island. She was Herreshoff's first victorious America's Cup defender design.
Columbia was an American racing yacht built in 1899 for the America's Cup races. She was the defender of the tenth America's Cup race that same year against British challenger Shamrock as well as the defender of the eleventh America's Cup race in 1901 against British challenger Shamrock II. She was the first vessel to win the trophy twice in a row
