I had an upholstery shop for a few years, doing lots of furniture, cars and an occasional boat. I moved to Oregon, and have been a truck owner-operator for the past 11 years. I still dabble in upholstery and canvas, though. I would like to get out of trucking, buy a nice blue water boat (I've been drooling over a Hans Christian 36 and a Union 36), and live aboard while learning to sail.
I'm kicking round the idea of a 'mobile' canvas/upholstery shop. Something like an enclosed trailer with fold down work tables and a generator for power.
I'm thinking that a shop that comes to the boat is better than a shop that requires moving the work to the shop.
Wow! We sure do wish you were close to us! We would want to hire you! Sounds like a great idea. Go for it.
