The ISHOF SaferSwimmer™ Float keeps you or your children safe during most swimming activities. It basically works as an inflatable float which is attached on a band to your waist and is carried in the current behind you. Now you might be thinking, well, that is not that revolutionary. You are right, this simply is not, however, the beauty comes in the fact that the device does not cause you to swim slower due to its resistance behind your body. When you swim, your body creates sort of a turbulent wave channel behind you with water moving in the direction of your swim. In more scientific fluid dynamics terms, this turbulent wave creates vortices which in turn produce a low pressure area behind the swimmer which causes the water to move along in the direction of the swimmer’s swim. The ISHOF SaferSwimmer™ Float takes advantage of this water flow and is basically moved in the direction of the swim on top of the wave with very little resistance. It is very similar to the idea of when cyclists or swimmers are drafting behind each other in their open road/water races. The second cyclist/swimmer always works a lot less than the first who has to plow through the air/water to create the forward moving channel.
