Gizmodo: "Regardless of your feelings about whaling, you have to admit the fight just got a whole lot more interesting. Check out this video of a Sea-Shepherd-manned (from Whale Wars) carbon-fiber, biofuel-powered EarthRace Trimaran blinding a Japanese whaling boat with lasers.
Looks to us like the laser is mostly for warning and intimidation, which probably works considering they're zooming around in a ferocious-looking 1080-horsepower, 78-foot trimaran. The crew manning the EarthRace is the Sea Shepherd society, which you might know from Whale Wars, where they're usually getting outwitted and outgunned in a boat nowhere near as cool as this one. The MV Steve Irwin, which is the ship followed by Whale Wars, travels a maximum of 16.5 knots—this EarthRace hits 50, which actually lets them chase down and intercept whalers."
