Here's a bit of bonus trivia: in the film Titanic, the officer on deck calls out Hard a' starboard when he sees the iceberg ahead and to the right. The helmsman desperately spins the wheel to the left, which is port. It looked like the filmmaker made a huge blunder, but in fact, British navigators in 1912 used the terms starboard and port backwards by modern standards when referring to turning the wheel.
This was a holdover from the days before ships had wheels to operate the rudder. If you want to turn a boat port (left), you push the tiller (the lever attached to the rudder) to starboard (right), so the full command to turn left was something like push the tiller hard to starboard. The transition to the logical modern terminology must have been difficult.
