First things First
Any port in a storm, Bporter. If you don''t have a compass handy, your lining up things at least gives you an idea of your relative bearings -- which is what you need to know. It doesn''t help to know that the guy that hit you was going from port to starboard because you saw a green light, or from starboard to port because you saw a red. If you see the bearing isn''t changing, you know to alter course and avoid the collision, regardless of what color lights you see.
