Port is the left - hand side of a vessel or aircraft, facing forward . Starboard is the right - hand side, facing forward . Since port and starboard never change, they are unambiguous references that are not relative to the observer . </P> <P> The term starboard derives from the Old English steorbord, meaning the side on which the ship is steered . Before ships had rudders on their centrelines, they were steered with a steering oar at the stern of the ship and, because more people are right - handed, on the right - hand side of it . The term is cognate with the Old Norse stýri (rudder) and borð (side of a ship). Since the steering oar was on the right side of the boat, it would tie up at wharf on the other side . Hence the left side was called port . </P> <P> Formerly, larboard was used instead of port . This is from Middle - English ladebord and the term lade is related to the modern load . Larboard sounds similar to starboard and in 1844 the Royal Navy ordered that port be used instead . The United States Navy followed suit in 1846 . Larboard continued to be used well into the 1850s by whalers . In Old English the word was bæcbord, of which cognates are used in other European languages, for example as the present Dutch bakboord, the German backbord and the French term bâbord (derived in turn from Middle Dutch). </P>
