Re: Starting a business?
The Baba may look "homey and comfortable" to you, but you are looking at it completely differently than a charter guest would be. They aren't going to live on it, so "homey" doesn't count for squat with them. What they will want is a big cockpit and/or a deck that they can lounge on. If they go below (and that's a big "if") then what they will be looking for is a sort of comfortable, airy, living room with lots of light. Oh, yeah, and a nice, big head that they can use when they need to.
You also need to take to heart the comment that this is not something you can do by yourself. You WILL need a mate of some sort. You simply cannot attend to all of the details of sailing the boat by yourself, AND attend to your guests at the same time. Ain't gonna happen.
If you plan to live aboard, then you have to have a marina that allows that. Not all do. Be sure you ask about that when looking for a place to keep the boat.
You may not have to serve full meals on day trips, but you will definitely need to have some refreshments and snacks available. On overnights, yes, guests are going to expect to be fed.
And, as others have said, a Coast Guard Captains license is an absolute requirement.
Good luck to you.
