Abstract: A swimmer's hand paddle simulating a human hand is formed from a generally planar member of PVC foam and has a central dome-shaped palm area for receiving the palm of the swimmer's hand. The paddle includes areas for receiving the thumb and fingers of the swimmer's hand. A wrist strap and one or more finger straps secures the user's hand to the paddle. The palm area, and also the areas which receive the swimmer's thumb and fingers, are provided with a series of apertures to allow the swimmer to feel passing water. The paddle is shaped to include an inwardly directed groove such that the peripheral portion of the paddle nearest the swimmer's second finger lies closer to the central palm area than do the peripheral portions nearest the index finger and ring finger. Also, an indented peripheral portion is formed between the swimmer's thumb and index finger.
