I should also give a shout out to CSR Marine, as I did my haul out there last year. They were great to work with, a little more costly, but super nice guys, (they gave me a great hat when I left). They're just inside the locks (freshwater), but they're just a boatyard, not a marina. My profile page has a few pictures of my last paint job if you're interested.
I used an Interlux product called "Fiberglass BottomKote with Ingarol" It went on really easy and is supposed to be a pretty good slim and algae reducer (so far so good). It's a seasonal paint, which means two years to me, but it was only like $30 a quart. I probably didn't need the Ingarol, but I'm never sure when I'll move out to the saltwater, so I thought I should be prepared.
