There was no race in 1937 (there was no suitable tide on a Saturday and at that time organised competitive sport did not take place on Sundays) nor from 1940–45 inclusive due to the second world war. The event was restarted in 1946 (naturally starting with a smaller number of entrants – 71 crews) and has taken place annually ever since, with the exceptions of 2004, 2007, 2013, and 2017 when the race was cancelled due to bad weather, and 2020.
