Navigation Rules
Believe it or not, P32 is spot on. I'm currently taking a course to get my captain's license, and interestingly enough, we just got through covering the Navigation Rules. Lighting is part of the Navigation Rules.The instructor started the class by explaining something that I always assumed I knew the answer to, but found I was wrong. I always thought the purpose of the lighting rules was to help you identify the type of vessel you were seeing. He informed us that the purpse of the lighting rules is to establish the stand on vessel and to aid in safe naviagation.To prove the point, he asked what it meant when you saw a single white light dead ahead. The answer was that it could be ANY vessel underway, or it could be a vessel less than 50 meters at anchor. He then asked how you could tell which it was? When we sat there pondering it, he said, you can't. It doesn't matter. You have to give way to a vessel you are overtaking, and you have to give way to an anchored vessel, so either way, the light has served its purpose, you MUST give way to it.A poweed vessel 12 meters in length or less must display (while underway) side lights, and either a stern light and masthead light, or a single all around light.Assuming Poor Old Sailor's boat is less than 12 meters, if he's running a combination of side lights and a single all around white light while he's sailing, he's technically wrong, but in practice, as long as he understands (which he acknowledges) that he gives up is "stand on vessel" priviledge when he's running lights that way, he should be OK.
