Sea-Quad lets you go from beach to surf and back again

The Sea-Quad is a sail-powered vehicle that can go from the beach into the water without any problems whatsoever. You steer the Sea-Quad with a bar connected to a kite above you, making it perfect for cruising around breezy beaches.

It's still under development, but when it's released it'll set you back $13,950. But really, this seems like the kind of thing that beach resorts will rent out, so hopefully people will get to try it out without dropping that much money on owning one. Via BornRich
