ABSTRACT:
A boom assembly is pivotally attached to the mast of a sailboard for pivotal movement between a use position and a storage position. The boom assembly includes a boom bracket and a pair of booms which are connected to the boom bracket. An elastic connecting member is attached to the bracket and is pivotally connected to the mast. The bracket includes a pair of camming surfaces which are engageable with the mast as the bracket moves from the storage position to the use position, and the camming surfaces tension the elastic connecting member to provide a frictional retention force between the camming surfaces and the mast which tends to retain the bracket in the use position.
