The human swimming speed record for a short stretch is 2.29 meters/second (7.5 ft/sec, 5.1 mi/hr), nearly eight times slower than dolphins. Aquatic engineer Ted Ciamillo decided to speed things up. As a result, he designed a single, flexible dolphin-like fin which attaches to both feet. By dolphin-kicking, the user easily moves through water at 8 mi/hr. The efficient gliding movement takes little effort and wearers have held a steady pace for hours on end. The monofin device is marketed under the name Lunocet. The adjective lunate comes from Latin and means crescent, the shape of the dolphin’s tail fin. Creatures on land and sea provide us with endless practical ideas designed by their Maker, including efficient swimming.
