发明名称 Water ski apparatus and method
摘要 An improved water ski apparatus and method are disclosed. A slalom water ski having an adjustable rudder fin is configured such that the rudder fin can be selectively and precisely moved in vertical, horizontal and diagonal directions in a manner such that each movement parameter can be separated from the others and is precisely moveable to within thousandths of an inch accuracy, in calibrated manner. Means are provided to enable complete removal of the rudder fin from the ski, and subsequent replacement while exactly preserving the last adjusted mounting position of the fin relative to the ski. An improved fastening technique for mounting the rudder fin to the ski body without loosening or stripping of the fastening members is also disclosed, as well as a method for fabricating a ski body that integrally incorporates the improved fastening members in the body of the ski.
