BOSTON - Petty Officer 2nd Class David Hamilton, a Coast Guard Station Merrimack River crewman, grabs the hand of his shipmate, Petty Officer 1st Class Jacob Correia, to pull him from the water during a 100-yard swim off the coast of Newburyport, Mass., July 13, 2011. The required training is to get the crew acquainted with the water temperature and check their suits for leaks, practicing different recovery techniques of people in the water, and locating where all their survival equipment is in their vest so that it becomes second nature.
