A *wave powered* boat. Neato.

I saw this on /. and wondered about one thing....with the wave powered propulsion, the crew feels NO waves?
(Have not RFA, so ...)
It is a really ugly boat... :)
Looks simple and robust enough to last a Pac passage.
Get yourself a couple of garage door springs and DIY!
