The Surf Shark helps humans swim like a fish

October 27, 2005 NEW IMAGES UPLOADED The Surf Shark and the Electric Dolphin are electric aquatic vehicles with a difference – instead of holding onto them as with all other diving and swimming aids, the Shark and Dolphin attached to your feet and propel you from behind, just like a fish and nearly as fast. The Surf Shark is the pick of the pair for speed, having two motors, each delivering 82 pounds of thrust and capable of pushing a swimmer through the water at more than 5 knots (10km/h) – that’s roughly twice the speed of Grant Hackett at World Record 1500 metre pace. The Dolphin has just one motor but makes up for its lesser speed with twice the life, being capable of delivering about half that speed for over an hour before needing a battery swap.
