Abstract
In the sports of bodysurfing and swimming, hand fins are worn for increased speed, stability, and maneuverability. Each hand fin has an internal compartment for the hand fin to be reliably held and controlled by the user. An upwardly angled, rounded peripheral lip provides lift and prevents pearling when water is flowing at the hand fin from any direction. A concave bottom and rocker creates lift and maneuverability.
