  • Patent number: 5173068
    Abstract: A body surfing apparatus comprising a body ski having a reduced hydrodynamic drag because it is made of smooth semirigid material for streamlining the upper body, and because it maintains its shape and resists local deformation. Certain edges of the ski are curved and located to minimize drag inducing scooping of water during planing. Side portions of the ski are provided to also reduce such scooping. One embodiment also includes thigh skis to increase the low drag planing area in the lower body region.
