I'm looking into buying my first boat and I want to get an idea of what the extra costs are going to be. I've done some research but I want to know how much anyone has paid to keep their boat on Boston's north shore. I'm looking at 21-24' fishing boats so does anyone have a general idea what it would cost for 1) a slip, 2) a mooring, 3) keeping it in a boat yard and using a ramp launch? I've seen rates online but those only seem to be at the huge marinas (and therefore huge rates). Thanks.
