Finning techniques are the skills and methods used by swimmers and underwater divers to propel themselves through the water and to maneuver when wearing swimfins.[1] There are several styles used for propulsion, some of which are more suited to particular swimfin configurations.[2] There are also techniques for positional maneuvering, such as rotation on the spot, which may not involve significant locational change. Use of the most appropriate finning style for the circumstances can increase propulsive efficiency, reduce fatigue,[1] improve precision of maneuvering and control of the diver's position in the water, and thereby increase the task effectiveness of the diver and reduce the impact on the environment.[2][1] Propulsion through water requires much more work than through air due to higher density and viscosity.[2] Diving equipment which is bulky usually increases drag, and reduction of drag can significantly reduce the effort of finning.[1] This can be done to some extent by streamlining diving equipment, and by swimming along the axis of least drag, which requires correct diver trim. Efficient production of thrust also reduces the effort required, but there are also situations where efficiency must be traded off against practical necessity related to the environment or task in hand, such as the ability to maneuver effectively and resistance to damage of the equipment.[2]
Good buoyancy control and trim combined with appropriate finning techniques and situational awareness can minimise the environmental impact of recreational diving.[3]
