Middle English sterbord, from Old English stēor (“steer”) + bord (“side (of a ship)”). Ships had to dock on their left (port) side because the steering oar on the right would get in the way, which is how the left became known as the port side.
starboard (plural starboards)
- The righthand side of a ship, boat or aircraft when facing the front, or fore or bow. Starboard does not change based on the orientation of the person aboard the craft.
- (nautical) One of the two traditional watches aboard a ship standing a watch in two.
