I am. Though I think I’ll get a place on dry land for the winters. Maybe a static home somewhere?
My research on living aboard suggests it can be quite hard in winter. Plus, do I want to be living on a boat as I creep into my dotage? Could be tricky.
There are quite a few second homers who like someone in their Spanish bolt hole during the winter, saw a site once, I'll see if I can find it.
