[Dear 2004, p.88] The 1930 Cup winner ''Enterprise'' had demonstrated the advantage of allowing the foot to bend this way, albeit using a completely different mechanism (the

For the Cup races, she was fitted with a Park Avenue boom.

[Dear 2004, p.87] During this time, she won four out of five races.
America's Cup
Following the regatta season, ''Endeavour'' commenced tuning-up trials against ''Velsheda''.
[Dear 2004, p.89] In particular, this was an opportunity to test her innovative quadrilateral jib to great success. By the time she departed for the United States, ''Endeavour'' had won eight races and placed second in three out of a total of twelve starts.
[Dear 2004, p.91]
Eight days before this departure, a pay dispute arose between Sopwith and his crew.
The crew were being paid £5 per week (about £280 in 2022 money), but wanted an allowance for "going foreign" and a share of prize money if they won.
Sopwith instead presented two counter-offers: either a base pay of £5 10s per week, with an increase to £6 10s if they won, or a base pay of £4 9s per week increasing to £8 per week if they won.
Unwilling to accept either option, and with Sopwith refusing to negotiate further, thirteen (about half) of the crew quit.
With only a few days' notice, Sopwith was unable to recruit professional crew replacements, and instead filled his crew with amateur yachtsmen.
This replacement crew was sourced by

This tour led to a protest by Sopwith that ''Rainbow'' had not followed the spirit of a new rule introduced to the competition that year that yachts should be fitted out with crew accommodations.
Below decks, ''Rainbow'' was spartan, while ''Endeavour'' even carried a bathtub in the captain's cabin.
The Cup Committee responded to the protest by allowing Sopwith to strip out large parts of ''Endeavour''s interior prior to racing.

The first race of the competition was abandoned due to light winds, ''Endeavour'' went on to easily win the first two races, and proved to be the faster boat.

''Rainbow'' won with 4–2. This was one of the most contentious of the America's Cup battles and prompted the headline "Britannia rules the waves and America waives the rules."

Following the America's Cup, she dominated the British sailing scene until, whilst being towed across the Atlantic to Britain in September 1937, she broke loose from her tow and was feared lost.

she described a "restoration urge" as being "inherent in the human nature" and said that she "immediately went 'Oh no'" when she realised the enormity of this task and that it fell to her. Meyer said she had to sell real estate investments to fund the restoration and that ''Endeavour'' was chartered throughout her entire ownership.
When ''Endeavour'' sailed again, on 22 June 1989, it was for the first time in 52 years.
In September that year Meyer organised the first J‑Class race for over 50 years, pitting ''Endeavour'' against ''Shamrock V'' at

She needed 90 professional sailors to crew the two yachts but could not afford to pay them; despite this, the appeal and prestige of the restored J‑Class was so great that she was inundated with several hundred applications.
''Endeavour'' cruised extensively and in 1999 joined the rebuilt ''Velsheda'' and ''Shamrock V'' to compete in the Antigua Classics Regatta.
21st century
Meyer sold ''Endeavour'' to
Dennis Kozlowski for US$15M in 2000.
In 2006, she was sold again, this time to Hawaiian resident Cassio Antunes for $13.1M.
In 2011, ''Endeavour'' completed an 18-month refit in New Zealand, during which a carbon-fibre mast and standing rigging were fitted and some changes were made to the deck layout. In summer 2015, it was reported that ''Endeavour'' was again for sale, with an asking price of €19,950,000.
