My interests change over the years. First bellringing. Then electronics, then narrowboat fitout, and now machining & metalworking, each for many years. Each required more space than the previous option. If I had gone fulltime liveaboard (on a narrowboat) at any point then my ability to change my activity would have been limited by the lack of space. Even a fatty would have been limiting, I could fill several with my tools and my offcuts that-will-be-just-what-I-need-one-day. So I never went liveaboard for this reason.
But further reasons existed. My partner was not keen but could have been pursuaded, but could not be relied upon to stay amenable, and hey, partners can need to be replaced and a new one might be less so.
And then there is the canal system. I fear that I could exhaust its ability to interest. Travelling around the Shroppie four times was about as many times as I wanted to do that bit. I suspect my fear is not well-founded but it is still there.
Now that I'm old and have to look after my back in particular, and am super-sensitive to cold, I am glad that resisted the temptation to go for liveaboard.
I always had a property to fall back to, but I'm glad I never went for renting it out, one of my sons has rented a property out and it has been hard work.
