The International Speed Windsurfing Class (ISWC) is a class of speed windsurfing boards that has developed over the last 30 years in order to facilitate high performance competition in strong winds and on flat water.
Speed windsurfing events are normally held on "flat water" as opposed to coastal surf; which means side-offshore wind directions with a strength of at least 20 knots (10 m/s).
The previous record holder is Finian Maynard having reached an average speed of 48.70 kn (25 m/s; 90 km/h; 56 mph) over the same distance at the same location, on 10 April 2005.
Speed Windsurfing events are normally held at venues with reliable, strong offshore winds and flat water.
In opposite to the venues for record attempts, accessibility is important as well as a not to difficult course to allow for proper race organization.
