An aquatic propulsion device includes an elongate member, a forearm support secured to the elongate member, a grip secured to the elongate member, and a paddle secured to the grip. The grip is positioned such that a person may place their forearm in the forearm support and reach and hold onto the grip. While wearing the aquatic propulsion device, the person may perform power and/or return strokes using their forearm and hand, such that the forearm support, the elongate member, and the paddle move in tandem with the forearm and hand. The aquatic propulsion device is characterized by a center of water displacement that extends beyond the hand, away from the forearm.
