English whalemen called it flenching, while American whalemen called it cutting-in. Flensing is the removing of the outer integument of whales. The former brought the whale to the stern of the ship, where men in a boat cut strips of blubber from the whale' s back, which were tied together and rowed ashore, where they were cut into smaller pieces to be boiled into oil in large copper kettles. The Dutch, meanwhile, eschewed this system, bringing the whales into the shallows at high-tide and flensing them at low-tide. This latter method proved much less time-consuming and thus more effective. Both parties only cut off the blubber and the head, leaving the rest of the carcass to polar bears and sea birds.
