Translation for non-shipdrivers:
At night, if you see the port side light of a ship to your starboard, slow or turn your ship to starboard so that you pass safely port to port or the other ship passes ahead of you. It is YOUR duty to maneuver.
At night all ships are required to display navigation lights. These are used to tell other ships about the direction the ship is facing relative to the ship viewing it.
Red, left, and port all have fewer letters than right, green, and starboard.
Full disclosure: It has been 35 years since I last had the deck.
