A swimming apparatus consisting of a generally cylindrical main body which is hollow and in which the front portion and rear portion are constructed and positioned in a streamlined fashion. The interior of the hollow, generally cylindrical main body is divided into a plurality of water-tight air chambers by a plurality of partition walls integrally fixed to the interior sides of said body. A diamond shaped face plate is affixed to the front underside portion of said body and extends outwardly therefrom. Attached by a hinge to the face plate is a pivotally mounted flange. The back and forth movement of the flange is somewhat restricted by wedge-shaped movement restricting members mounted on the underside of the face plate in front of the pivotally mounted flange and by wedge-shaped space maintaining members affixed to the back side of the pivotally mounted flange itself. A wall extends downwardly from both sides of the generally cylindrical body behind the face plate. In the space between said walls and affixed to them perpendicularly is a handle to be grasped by the user and behind said handle is an arm supporting strap affixed perpendicularly to said walls.
