1. An aquatic propulsion device comprising:
- an elongate member;
a forearm support to be worn on a forearm of a person, the forearm support secured to a first portion of the elongate member, the forearm support including a first portion having a curved generally c-shaped profile;
a grip secured to a second portion of the elongate member; and
a paddle secured to the grip, wherein a person can place a forearm in the forearm support and can reach and hold onto the grip with a hand and move the grip with the hand such that the forearm support, the elongate member, and the paddle move in tandem with the hand and the forearm, wherein a combination of the forearm support, the elongate member, the grip, and the paddle is characterized by a center of water displacement extending beyond the hand away from the forearm in a direction generally indicated by a line from a portion of the forearm support toward a portion of the grip, the center of water displacement offset relative to a midpoint of the grip in a direction generally indicated by a line from a thumb-side of the hand toward a fourth-finger-side of the hand.

Abstract
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.
