YP Patrol Boats

Yard Patrol craft are used by the United States Navy for training and for research purposes. They are designated as YP in the Hull classification symbol system. The YPs are used to teach familiarization with water craft, Basic Damage Control and underway instruction of Basic to Advanced Seamanship and Navigation. Yard Patrol craft provide realistic, at-sea training in navigation and seamanship for midshipmen at the U.S. Naval Academy in Annapolis, Maryland, and candidates at Officer Candidate School, Newport, Rhode Island. These craft can cruise for 1,400 nautical miles (2,600 km) at 12 knots (22 km/h) for five days without refueling.
