ABSTRACT:
In the sport of bodysurfing, hand fins are worn and reliably held on the surfer's hands. Each hand fin has longer outer and shorter inner rails for better stability and guidance, a keel for straight tracking through a wave, and curved channels for creating more lift and increased speed through the wave. A peripheral lip provides lift even during steering maneuvers.
