ABSTRACT:
A device for connecting a sailmast to a sailboard comprises a mast-connecting universal joint, which is connected at one end to the mast and is permanently fixed thereto or can be only arbitrarily separated therefrom and is connected at its other end to a supporting member, which when the device is in position for use is received at least in part by a recess in the upper surface of the sailboard so as to be positively connected thereto. To provide for an overload coupling, the supporting member is constantly biased by a spring so that the positive connection can be eliminated only when the spring force is overcome.
