Dude, I can't believe you have the same problem! There must be a world wide secret society of them! Good grief, they do it in my boat even when I'm on it and I haven't seen them!On the other hand, thinking about and discussing sometimes arcane aspects of sailing and cruising helps us to better understand the systems on our boats.
For a more pressing topic, how do I find and get rid those people who keep hiding stuff on my boat? It is really getting annoying. I know it's neither my wife nor I who would do such a thing. Boat projects would go more quickly if only these denizens would cease with their antics every time I turn my back.
