A monofin is a type of swimfin typically used in underwater sports such as finswimming, free-diving and underwater orienteering. It consists of a single or linked surfaces attached to both of the diver's feet, emulating the fluke of Cetaceans like whales or porpoises. Even though the diver's appearance might be reminiscent of a mermaid or merman, monofin swimming is not the same as mermaiding.
Finswimming is an underwater sport consisting of four techniques involving swimming with the use of fins either on the water's surface using a snorkel with either monofins or bifins or underwater with monofin either by holding one's breath or using open circuit scuba diving equipment. Events exist over distances similar to swimming competitions for both swimming pool and open water venues. Competition at world and continental level is organised by the Confédération Mondiale des Activités Subaquatiques (CMAS). The sport's first world championship was held in 1976. It also has been featured at the World Games as a trend sport since 1981 and was demonstrated at the 2015 European Games in June 2015.
Constant weight (CWT) is a freediving discipline recognised by AIDA, the International Association for the Development of Apnea, in which the freediver descends and ascends using their monofin and/or with the use of their arms without pulling on the rope or changing their ballast; only a single hold of the rope to stop the descent and start the ascent is allowed. Constant weight is one of the eight disciplines considered for international competition, the others being constant weight bi-fins (CWTB), constant weight without fins (CNF), static apnea (STA), dynamic apnea without fins (DNF), dynamic with fins (DYN), free immersion (FIM), and dynamic apnea bi-fins (DYNB).
Finswimming has featured as a trend sport at the World Games since the inaugural 1981 World Games held in Santa Clara, California.
The Finswimming World Championships is the peak international event for the underwater sport of finswimming. These are conducted on behalf of the sport's governing body, Confédération Mondiale des Activités Subaquatiques (CMAS) by an affiliated national federation.
