In 2003, a commercial Icelandic fishing boat crew was processing their catch from the day after returning to shore. This entails crewmen standing in shallow water as they clean and gut their haul of fish. Captain Sigurdur Petersson, a rugged leader of men known as “The Iceman,” supervised his crew from dry land.
This day, the entrails, blood, and activity attracted a 660 pound shark, intent on feeding. Unseen by the crew in the water, the shark swam toward the diligent workers. Captain Petersson scanned the water and somehow saw the great hulk of a fish approaching. He spied the fin and knew his men were in grave danger. The majority of shark attacks occur in shallow water; the especially violent and sometimes fatal shark attacks were often precipitated by the presence of blood, dead fish, and movement in the water. This was a recipe of doom for the unsuspecting crew.
Petersson acted without hesitation and went on the offensive. He sprinted into the water and seized the predator by its tail, with his bare hands. Violent thrashing ensued as the crewmen watched, mesmerized by the struggle. Petersson prevailed. He dragged the shark onto land, unsheathed his knife and stabbed it to death.
Now that’s physical toughness!
