发明名称 Water ski apparatus
摘要 Apparatus for use with a boat, comprising an elongated bar having one end pivotally mounted on the side of the boat, the bar extending from the boat side so that a skier may grasp the opposite end of the bar or may tie his ski rope thereto. The bar is braced by means of a cable secured to an intermediate part of the bar and connected to a forward part of the boat, such as to the deck cleat. A further cable has one end connected to the bar and its other end connected to an upright mast. The pivot connection for the one end of the bar is in the form of a mounting plate which is secured to the side of the boat. The mounting plate has spaced ears between which the bar end is disposed, and a pin is disposed through holes in the ears and the bar end to provide a horizontal pivot.
