My friend and his wife started married life on a 32' ex Harboro' Marine / Anglo Welsh hireboat, siad to be half of a wooden butty with a steel counter attached.
One main cabin plus a small galley and heads, complete with sea toilet. They used to go to the public baths once a week for a private bath.
They lived for several years on the S & SY at Mexborough Wharf, and regularly used to get woken by some bumps from a string of Tom Puddings waiting for the locks.
Since then they've had several other boats, farms and animals and built their own house.
They clearly thrive on doing things the hard way.
BTW their honeymoon was backpacking across North Africa.
