Mighty fine looking ship! My neighbours in Portland, Maine, USA. live on a similar boat, North Sea trawler, they call it. Built in Scotland, 1965.
They stay in a marina, mostly, but have traveled around Newfoundland and lived in Greenland, for a few years. You will never see them below Cape Cod, though. That is their southern range....
Sounds like you have the living on the mooring part figured out.... I am just getting ready.
