ABSTRACT:
A mast-connecting universal joint is provided, which is connected at one end to the mast and is permanently fixed thereto or can be only arbitrarily separated therefrom, and which is connected at its other end to a supporting member, which is biased by a resilient element and in position for use is positively held in a slide, which is longitudinally slidably guided and adapted to be resilient locked in a groove of the sailboard. The resilient element constitutes a return spring for the supporting member when the mast is in any position of use, and a return spring for moving the longitudinally slidable slide to a position in which the slide is releasably locked.
