I discovered this post today! and was fun to see the floating workshop .... hi hi .....but not the first I see, I bought my RF 40 mill for over 15 years to a guy who also had his floating workshop, which appeared around the island in a boat similar to yours, equipped with: lathe, milling , band saw, compressor etc..
when he arrived to a new port, pulled the boat in dry dock and took some of the machines out of the boat, and was offering its services to other boaters.
the mill not returned to sail the seas ..... and stayed on the island.
