  • WATER SKI FIN
    Publication number: 20200172208
    Abstract: A fin for a slalom water ski includes a planar body with a convex leading edge and a slot proximate such leading edge. The slot has an arcuate front or leading edge and a wavy rear edge defined by alternating crests and troughs or projections which allow the fin to be smaller without compromising its ability to support ski acceleration. The smaller size allows the ski to be turned more easily. A line of small holes extending in a row proximate the leading edge of the fin body can achieve the same result.
