When going into a port or harbor, you should keep green buoys on your left. When leaving a port or harbor, you should keep green buoys to your right. A good way to remember this is the phrase "Red, Right, Return." This phrase means that you should keep Red buoys on your Right (thus keeping green buoys on your left) when coming into a port/harbor (Returning).
Nuns are red.
