Also at Fort Adams there is the americas cup museum right there in newport. Not sure of hours but you should for sure check out Fort Adams, do a drive through and the museum is right there.
Taking a drive up there tomorrow for a day trip with my non-sailing girlfriend. We are going to hit the mansions and maybe the cliff walk, touristy crap. I'm going to need a sailing fix though, where is a good museum kind of place? Herreshoff Museum in Bristol?
