Abstract

A sailboard or surfboard (30) having a fin (32) and a skirt (36) extending aft of the tail edge (34) of the board. The skirt (36) is mounted to the sailboard in a manner so that the skirt assumes the contour of the water when sailed. Adhesive or a clamp plate is utilized to secure the skirt (36) to the board (30). The fin (32) includes a fin base (60) and a foil (62). Foil (62) is positioned aft of the fin base (60) so that the trailing edge (64) of the foil (62) is aft of the fin base (60).
