I would appreciate business ideas involving my 2 classic boats:

I own two classic 51ft boats, both monohulls:
Number One fully equipped to live on it, 2 big diesel engines, full kitchen, bathroom, sleeping area, etc.
Number Two a restauration project, maritime heritage so to say. Maybe something like a "life woodworking workshop" until finished.

Ideas to generate income with one of the boats (without selling it) would be great.
There are already lots of boats offering fishing tours, which are much more suitable for the purpose of fishing (they are built for it), so something different would be great. To consider is also the location here - the UK's southcoast, so it's not the Med or Caribbean or Florida.

Best Regards, Tidal
