Sea Shepherd is a vigilante splinter of Greenpeace started by Paul Watson, a cofounder of the environmental group who was exiled for the bellicose act of throwing a seal hunter’s club in the ocean. Hammarstedt himself found Greenpeace too gentle for his tastes. “Greenpeace is a protest organization,” he says. “We are a law-enforcement organization. Our goal is to shut these guys down.” To that end, Sea Shepherd rams ships, hurls stink bombs, and fouls propellers. In 2010 the front of its yacht was shorn off by a whaling ship, an event captured by a film crew from Animal Planet’s Whale Wars, providing Sea Shepherd with attention far more valuable than the $1.5 million vessel. “We’ve never lost a game of high-seas chicken,” boasts Hammarstedt.
