I've put this before, but my dad dropped lucky. He has a narrowboat, is on it lot. But also does have a house. He has a private mooring and pays £25 a week for. He rents a bit of land off a dairy farmer. Only 4 boats there, 3 permanent live a boards and my dad's. Very very rural quiet little spot. So for £100 per month he has his mooring with some land and has a garden and a few sheds and a bit of space, off road parking and water tap on mooring. He calls it his dead man's shoes spot and was lucky to find it. He's had it 20 years plus now. He loves it.
