Woodenboat is neat to see when there's a class going on with projects to view and people to talk with. Other than that, the store is interesting, but simply has what's in the catalogue. If you're going to be that far 'East', check out Searsport Penobscot Marine Museum
The museum is based in sea captain's houses. Belfast also has a very pretty main shopping street and several boatbuilders that might not shoot you if you stuck your nose in. (Brooklin likewise.) The Maine Maritime Museum in Bath is definitely worth a visit. Maine Maritime Museum
If you can get there before Columbus Day weekend, they offer tours of BATH IRON WORKS - a mind-numbing state of the art facility that turns out incredible vessels for the U.S. Navy. We went by there this summer and saw a brand new destroyer at their dock. Further south you can visit the Rockport Apprenticeshop (check out the Farnsworth Museum while you're there too, to get your Wyeth fix). If you head inland a touch, Sabre might like to show your around too. Before leaving Maine I enjoy stopping at The Landing School in Arundel, to see what they are up to. ttp://www.landingschool.edu/ Don't forget to eat lobster. $3.50/lb when we were there this summer - cheaper than steak.
