ABSTRACT:
A swimming system for maximum efficiency in water has a single foot fin with a large fluke and two foot openings leading to foot pockets separated by a cushion. A series of water directed openings extend rearward and outward from a line above the toe portions of the pockets diagonally through the fluke to a line near a tip of the fluke on a rearward portion of the fin. A fastening surrounds the fin near instep areas of the foot-receiving pockets. A leg sheath has a corresponding lower fastening, a cushioning divider between legs and an achilles cushion above a heel portion to streamline the sheath. A reinforced upper waist band fastens to a jacket portion with hand openings which overlie hand fins formed of flat circular plates with finger and palm cutouts mounted between two pieces of synthetic dolphin skin. The helmet with an annular neck encircling cushion completes the streamlined entire body covering with a synthetic dolphin skin exterior. A blow-hole rearward of a neck portion of the helmet has a raised forward edge to promote air entrapment in a snorkle which leads through the annular cushion to a mouthpiece. A water-tight snap seal covers a forward opening in the mouthpiece. Nostril blocks are provided in a nose cavity. Eyes are encircled by seals which support curved lens for removing water distance distortions. Tubes lead from eye areas to the mouthpiece for pressure equalization. Screened ear holes permit pressure equalization and hearing.
