First there was cruising above the surface of the water with the Jetlev R200, and then came the not so cool Aquaskipper, where you use human power to propel yourself across the surface of the water in a very lame looking contraption.
And now we have the Subwing, where you get to glide under water as a dolphin would. It’s basically a small wing you hold on to while being pulled along by a boat. The Subwing allows you to move sideways, twist, and even dive. Based on what I saw in the video below, one could hurt themselves if not careful. But then again, that can apply to anything.
