The aim of the TSASA is to promote trailerable yachting through a program of cruising, racing and social events.

The TSASA covers all classes of trailer sailors, almost any trailerable yacht that has a cabin where members may sleep. Membership is open to anyone interested in trailerable yachting.

The Trailer Sailer Association of South Australia began in 1967 when most trailerables were of timber construction and home built. Membership has grown from those early beginnings and is still growing.

The TSASA has an extensive calendar that covers the main interests of the club, those being cruising, racing and social events.

Cruising allows the TSASA to travel to far-away places such as the Whitsunday Islands and other places in Australia. Local waters such as Coffin Bay, always prove popular. The Murray river is almost certain to be visited during the year.

The flagship of the racing events has always been the Rosebowl, a handicap race from North Haven to Glenelg and return. Other races are spread throughout the season and include Port Vincent.
