Abstract
A thin top shell of aerodynamic contour is secured over a jump ski base smooth flow of air over the top of the ski during a jump, without interfering with the on-water performance of the base. The shell has a bulbous tip portion, a first portion of airfoil cross section aligned transversely of the ski in front of the central binding area of the ski, a second portion of airfoil cross section aligned transversely of the ski behind the binding area and a tail portion of airfoil cross section aligned longitudinally of the ski. The first and second airfoil cross sections have their thicker, more sharply curved sections disposed toward the inside edge of the ski, and the tail portion has its thicker, more sharply curved section disposed toward the front of the ski.
