Finswimming Finswimming is a style of swimming which uses a special kind of fin to achieve greater speed through the water. The first to try out these fins was the French Lieutenant Collier in 1927. The dolphin shaped fins were transformed into monofins in the 1970's. There are 3 disciplines: surface, apnea and immersion; a center-mount snorkel is used for surface races, a small pony-bottle for sub-surface immersion events, and no breathing aid at all is used in breath-hold apnea sprint races. Finswimming is governed by the Confédération Mondiale des Activités Subaquatiques, which was founded in 1959.
