The Tasar is a 14-foot (4.3 m) fiberglass 2 person sailing dinghy with a mainsail and jib. Designed by Frank Bethwaite of Sydney in 1975, the boat was technologically advanced for it time and continues to evolved. Aimed at a husband-and-wife or parent-and-child crew hence no spinnaker, it is designed for a combined crew weight of around 140kg. The hull weighs 68kg, and is of sandwich foam construction. The wide beam and a cockpit designed for comfortable hiking make the Tasar easy, fun and very exciting to sail in winds up to 25 knots (46 km/h).

The Tasar is an international class, with strong fleets in Australia, USA, Britain, and Japan. The class gained status from the World governing body for sailing in November 2001 permitting the class to hold a officially recognised World Championships.
