The son of a Southend builder and contractor, William Maddison followed in his father’s profession. At the time of the 1920 Olympics, Maddison was an established yachtsman racing his own 18-foot yacht Cutty Sark but crewed for Cyril Wright aboard his yacht Ancora to help them win the 7-metre gold medal at the Antwerp Olympics. Like his fellow crew members, Maddison was a member of the Royal Burnham Yacht Club. Maddison sadly died in 1924 at the age of 41 just three days after racing in his own yacht Nancy which finished second in the Royal Caledonian Yacht Club’s East Coast One-Design race on the River Crouch.
