Eugene Riguidel is a French yachtsman who was an early convert to racing trimarans. In 1975 he raced a 33 foot  Crowther Kraken 33 in the AZAB race finishing second to Nick Keig in the 37 foot Three Legs of Mann. He went to Derek Kelsall with his sponsor the French magazine VSD. He campaigned three successful designs from Derek Kelsall. VSD1 was a development of the GBIV design and Eugene lost her at the end of the Route De Rhumb race in 1978 when he ran aground on the reefs of Barbuda just before arriving in Guadeloupe. A replacement VSD 2 followed this development on with larger floats, and more protection in the cockpit, extensions for the bunks on the main hull. He competed in the 1979 Transat en Double two handed transatlantic winning the race. The boat was then fitted with foils on the rudder and main hull.  In 1980 an attempt on the New York to the lizard record ended with the boat tripping over its foils as it surfed down a wave and pitch poling. Its is thought that the foils buried at the wrong angle as the wave was so steep and the stern was lifted, so the bows failed to lift because of the foils  His OSTAR 1980 was also dogged by bad luck namely loss of the centre board after 10 days and finishing 19th in 24 days. Under a variety of name this boat entered many races and competed in an Atlantic record attempt again. Her racing career over in 1987 she was sold and in 1997 was found abandoned in the Balearic Islands. Restored by Stuart Rogerson she sailed the Atlantic several times and had a great renaissance under owner Stuart Rogerson until her loss in 2018. Finally Eugene commissioned an 88 foot trimaran from Derek Kelsall called the William Saurin in 1983. She  was the pinnacle of Derek's racing design career and again the largest trimaran in the World. After her racing career ended the trimaran renamed Safir became a charter vessel. Today Eugene is a keen environmentalist and campaigner.
