The centre is the waist or well deck and the sides of the waist are the bulwarks. These stretch from the fo’c’sle aft to the poop. The left-hand side of the vessel looking forward is termed port and the right-hand side is starboard. The portside used to be called “larboard”. It was found that confusion arose in rough weather owing to the noise of the wind and the sea, so the name was changed to one that sounded quite different even in such conditions.
