Boatdreams1984, Welcome to the Forum.
You don't say if you own a boat, or what size/type. This would impact the type of marina and facilities that you are looking for. Do you need year round storage or summer only?
If you are planning to commute from Concord, that's one thing. If you will be renting a (non-waterfront) camp, that's a different set of issues. Presumably, if you rent waterfront, there's a dock.
Maybe a boat club is the answer?

Unlike many, I use rack storage in the winter and in the summer I have a dock. I suspect there are some who pay for summer valet and trailer the boat home for the winter, so I think if you valet store for the winter, you've got a head start in staying there for the next summer.
Mostly, I don't think you'll find a lot of gho here, don't go there, on this forum. Most of us are happy where we are, or we move. It is easier to get your foot in the door someplace so you can enjoy the boa, and then keep your eyes open if you want to relocate.
