I get people being content to live in a very small space. And some of Lee Blake's ideas around storage etc in vans could also be applied to narrowboats. But I don't get the enthusiasm for a full-time live-aboard to want a Wilderness Beaver. Unless I have misunderstood: GRP, so more fragile Outboard engine, with no ability to heat water or boat. In the UK solar panels can power phones, laptops etc, but unlikely to consistently produce enough for heating (boat or hot water) or cooking Petrol, not diesel, so fuel not readily available and will have to be stored in jerry cans increasing the fire risk Trailability isn't an advantage for a live-aboard, unless there is a strong desire to visit the disconnected parts (Mon & Brec, Scotland etc, or to take it out of the water for maintenance
