Aye, cold in winter, bit like a caravan, specially in the UK. But if the boat was a liveaboard moored somewhere like Gibraltar, and say 52 ft. you’d have plenty room and no freezing weather. You could get something like that for the price of a crummy semi in Scunny, and teach yourself all about it while in residence and having the adventure of a lifetime! Mrs Gurn isn’t too keen mind – likes the garden and creature comforts, etc. etc.
