Re: Give way when hoisting the main?
jackdale - that one makes perfect sense to me. You are required to mark your position at anchor, as an obstacle to be avoided. You are going to need a working anchor light, or stand watch all night to alert other boats if your anchor light is non-functional for some reason.
I am mostly curious about what happens when you are doing your best to avoid a collision and one happens anyway due to the actions of another. It can get particularly hairy on a crowded river during weekends and holidays on the Chesapeake. As a result I avoid sailing at those times, rather than deal with boaters who have no idea what the ColRegs are, and the only radio station they have tuned is Top 40 blasting out loud enough that the entire river can marvel at their lack of taste in music.
