I am quite aware of that, but the op has not stated if this boat is continually cruising, the fact that he says two months on and two months off, makes me think otherwise.When continuous cruisers make arrangements to stay for a while, they make the arrangements with the owner of a mooring (marina, boat club etc) not with an individual. Also BW allow them to stay on short term moorings in the winter, for the appropriate fee.In my opinion, if the boat in question is a continuous cruiser, then he is breaking BW regulations by staying on this mooring for two months on and two months off. And as I stated in my previous post, if he is not continuously cruising then he will have (or should have) paid for a permanent mooring elsewhere. What happens in Winter, when both boats want the mooring?
