A rogue wave off Antarctica has dealt a major setback to conservationists' efforts to thwart Japan's annual whale hunt. The wave hit the Sea Shepherd Society's Brigitte Bardot as it chased the Nisshin Maru factory ship, badly damaging one of its pontoons, the BBC reports. Another boat, the Steve Irwin, is racing to help the stricken vessel. The group says the Bardot's 10 crew members were not injured, and the boat is in no danger of sinking in the icy water, reports AP. It will be towed to Australia for repairs, leaving a third boat, the Bob Barker, to hunt Japan's whaling fleet alone.
