Monty Python: "RUN AWAY!"

Okay, now burn 'em.

If they coated boat hulls with this stuff, would they cut through the water more efficiently?

No, that's how you make hovercrafts. :-P

But seriously, smooth hulls are actually bad for speed. Ideally you want little pockets of air to make a good boundary for the laminar flow of water going past. Some people even sand the hulls of their racing boats. Think about the dimples on a golf ball, same idea. Although it'd be an awesome product for the windshield of a boat. =)

Yep good point, and if you look at/touch shark skin, it's essentially sand paper; helps them move faster through water apparently.
