Berth Capacity

Linear Docks:550 Feet


The Entrance to the marina is on the south side of the main pier. Please be careful of ferries leaving and entering the marina basin. Ferries may be restricted in their ability to maneuver so plan accordingly. We ask that vessels with a wide beam do not berth directly across from the ferry float (large steel float) in order to give the ferries swing room on their approach. The Drop off/pick up are is located at the end of the finger closest to the ferry float and should be used only when a ferry is not trying to enter or leave the marina please. Additional caution is required when approaching the float that is located closest to the beach. The inside between the shore and float is VERY tidal. Please be aware of your draft and tide height when berthing on this float. The mooring field is located on the northern side of the main pier. They can be reserved by using the application on your smartphone or tablet. There will be a dinghy for public use on the floats. Again, please be careful when entering and leaving the marina as visibility is bad at the corner of the pier. Stay along the shoreline if possible. Please return the dinghy promptly after using for other boaters. Thank you and enjoy Spectacle Island!

The island is a treasure! We enjoyed the Trillium’s beer garden Sat afternoon, then had the whole place to ourselves for the evening. The trails are superb, as are the views of Boston. Very calm seas-even in the aftermath of hurricane Dorian. We will return from our slip in Boston!

Very rocky due to wakes created by high speed ferry. We have a 39’ sailboat and our boat got tossed around similar to being out in a small craft advisory. Couldn’t swim off the boat due to the chop. Dinghied to the beach, but our dinghy was getting trashed so back to our sailboat we went. Quieted down after 8pm.

The booking was good. You were very responsive to adjust the rate down to just a day rate. However, I couldn't hail anyone at Spectacle Island on Channel 69 and a DCR ranger said to just take any open mooring if we had a reservation.

Beautiful spot to set up for the day. Moorings are easy to use and the staff at the location were great. Look forward to them putting more moorings in soon. They fill up quickly.
