It's a pretty spectacular feeling being on a mooring ball in downtown Boston. We were here for the 4th of July and got to see the USS Constitution make its "turn around tour" decked out with flags and escort ships and perform a gun salute to the US Coastguard. And we had front row seating for the fireworks show performed from a barge on the 3rd. A-MAZE-ING. The marina is very nice with great new docks, a protected dinghy dock, helpful staff, secure gate, and services. There is immediate access to all the great downtown sites and sights. Unfortunately the airport is very noisy most of the day, including evenings, there is a train tunnel directly under the mooring field and docks that you can hear and feel trains going through most of the day, and the ferry and charter terminal is right next door so you get big boat wake all day long.
