This looks really cool!! Next time I go to OBX I want to take one of these with me! I stumbled across these pics through some random google search. (How I got from surreal art, to dolphin inspired vessels I don't know?!)
This boat, made by Innespace Productions, is intended for underwater and surface navigation, but its main strength is that it can jump out of water with the same accuracy as a dolphin. Check it out!
