ABSTRACT:
A mast base for a wind surf-board adapted to have a mast cardanically fastened thereto. The mast base is releasably latchable in a sleeve or in an aperture within the body of the sailing board or wind surf-board, and includes spring-elastically adjustable latching elements which engage in corresponding recesses in the sleeve or aperture within the wind surf-board. An externally manipulatable adjusting collar is connected to a clamping nut or toggle member to bias the latching elements so as to exert variably selectable latching forces.
