ABSTRACT:
In construction of a sandwich type ski including a core and upper and lower surface guards sandwiching the core, a prismatic reinforcement having high Young's modulus is present about the bottom middle of the core so that presence of the reinforcement should resist concave warping of the ski in the lower sliding surface at load application in use via dispersion of compression on the boundaries between the core and the reinforcement.
