The attached image gives an idea how beautiful Boston is from the water (the reality is much more spectacular). We were on a mooring about 50 yards from the Boston Aquarium, which is just out of view to the right in this image. We got a guest mooring for $50/night at the Boston Harbor Sailing club. That includes launch service and dinghy dock at Rowes Warf -- no other amenities. A good deal, IMHO.
