Powered by sails, the Sea-Quad amphibious vehicle can go from land to sea without any modifications. Riders “steer the Sea-Quad with a bar connected to a kite above you.” Pricing start at $13,950. Video after the break.

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.
