Landing craft
watercraft designed to transport amphibious forces and cargo to a beachhead from nearby embarkation
Landing craft are small or medium sized boats made to land at a beach. They help military troops move from their transport ships to the beach, when they cannot use a port. They are also used to deliver supplies and vehicles for troops. To get onto a beach, the landing craft has to be flat-bottomed. The lack of a proper keel makes them uncomfortable in rough seas.
