Marinas cost a stack more, obviously. I've always moored on farms, in thirty years never paid more than £500 for the farm mooring, plus the EOG. No facilities, no power. If you parked a sinker up here, without anyone to keep an eye on it, it probably would sink. It rains a lot and bilge pumps fail a lot.
I'm making an assumption as to what a CRT mooring costs as the EOG is meant to be half. Farm moorings on the Macc are like hen's teeth, but a couple of folk on here have settled on my mooring when we had vacancies.
