How about bugout boats?

[Mortblanc]

You should see the state of some of the canals since the Covid hit and they can not be maintained. That is all done by the Canal and River Trust now and people live on small boats on the canal system everywhere.

You do have a canal use fee of about 150 pounds, but that is offset by not having to pay council taxes and you definitely see where it is going if you are moving along the canals constantly. Lots of dredging, trimming and lock repairs going on.

The boat you have pictured is a GRP river cruiser and you can live on one as a "continuous cruiser" if you meet the regulations, which include moving every 24 hours to two weeks, depending on the place and season. There are thousands of people living in them and posting on you-tube, pretty good entertainment watching them do repairs and maintenance during COVID mumbling "lefty loosey" with plasters all over their fingers!

Since you don't drive you would fit right in. Most of them float about smashing into one another, shouting and throwing things about and then showing film of their abuse on-line like it was Russian dash cam footage.

However, using one as an escape mechanism is risky. You are restricted to usable waterways, often too narrow to turn about and leave. And you will find that almost every inch of that shore line is privately owned by folk that do not really like the "ditch people".
