why I favor having a gun on board. I've used Plan A when a drunk and his girlfriend thought my boat would be a great love nest. I had seen and heard them and 'knew' that was their plan. Sure enough within 10 minutes they were getting ready to climb aboard. (I was the only boat at a a dock in an empty marina). When they heard a loud "Don't even think about it!" from me, they were gone in a flash.

Again, while I favor the gun on board concept, I'm not sure I'll ever act on it....
