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.
