Endeavour challenged for the 1934 America's Cup and raced New York Yacht Club defender Rainbow.
However, the campaign was blighted by a strike of Sopwith's professional crew prior to departing for America.
Forced to rely mainly on keen amateurs, who lacked the necessary experience, the campaign failed.
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."
The mighty J-class is still being sailed today and can be seen in a classic regatta which will be held along with America's Cup in Bermuda 2017.
