It’s very easy to find the F/V Seven Bells (F/V stands for Fishing Vessel). If you are good with maps, there is one below.
The lobster cruise leaves out of Dysart’s Great Harbor Marina, which is located at
11 Apple Ln.
If you would like to use the free Island Explorer bus system, visit their website here: Island Explorer Bus System for schedules and routes. Bus #7 aka The “Southwest Harbor” bus drops you off about an eight minute walk to the marina. You can also have them make a special stop at marina entrance.
