Brain is correct. I'm a volunteer for the United states naval shipbuilding museum. Parking is a little hidden. You go to the address we have which is 551 South St Quincy MA. You can drive straight pass the building's on your left. Then take a left. Then you will see the ship clear as day. Brain Bulkowski is also correct, there is a address for GSH that will bring you directly to it. But GSH is closed for good now. Not sure if Google will take it down.
The location pin on Google maps is wrong at the moment, i filed an edit, maybe it will be right soon. The museum is the ship with turrets nearby, and there is a pin called 'ghost ship harbor' which is where the parking is, sort of. The signage is easy to miss. Head for the ship and it will become clear.
I get around in the wheelchair is there anyway I can get into the museum? If it is not accessible is there a video tour of the museum?
Parking is easy, not an issue, just don't block railroad tracks.
