ABSTRACT:
The invention relates generally to masts for the rigging of sailing boats, such as for example centerboard boats of the "FINN" series, and is directed to the problem of increasing the elasticity of known masts of wood or tubular metal. A mast according to the invention is provided with a longitudinal slot, the lips of which may be brought to face each other and are fixed together in places in a non-continuous manner. By this means the mast is given a substantial capacity for elastic torsion, resulting in improvement in its performance.
