About


Three Mile Harbor Marina is a full service marina and boatyard with a well stocked ship's store and a newly constructed club house. The Marina has floating docks and electric or water hookups at each slip. The new clubhouse has restrooms, showers, laundry, handicap access, and a small business area with air conditioning. The outside seating has grills available for all marina guests.

The Three Mile Harbor Marina staff assist with transient moorings adjacent to the western side of the channel, half way into the harbor. A dinghy dock is located on the east side of the C-Dock for transient mooring customers use. We do not provide a launch service for our moorings.

Three Mile Harbor Marina receives transient boaters between the operating hours of 8:00 am and 4:00 pm, 7 days a week, in season. Check-out/Check-in time is at 11:00 am. Please use VHF Channel 9 to contact the marina during regular operating hours when your vessel is well within Three Mile Harbor and we will offer you full service dockage and support, including any related marina services during our regular, scheduled hours of operation.

Should you require a late check-in or departure, additional charges will apply. Please contact us in advance so we can properly support your boating trip plan. Thank you and Happy Boating from the staff at Three Mile Harbor Marina.

We had our initial reservation at three mile but were moved to Halsey's Marina. It is part of the same family of marinas but a mile north. We absolutely loved the facility and grounds and staff. Les Black is super helpful and knowledgeable. He would not let us tie up to our slip without his hands on help. The marina has gas grills. Local seasonal boaters who are very friendly. The laundry has new washer and dryer and they are free to use. It’s very close to East Hampton center and 30 minutes from Montauk. Strongly recommend Haley’s. The nicest marina on our trip. .

Fantastic experience all-around. The bathhouse and laundry room were new, clean and well-maintained. The marina is extremely well-protected. The dock hands and Dockmaster were all very supportive. We had a very nice four night stay here and recommend it highly. It can be a little tricky to find the first time you come here. Just call ahead and they’ll explain it, and there’ll be no problem. Or set your navigation system for Three Mile Harbor Boatyard instead of Marina and that will work too.

Staff was very accommodating, dock were well maintained. However, there are NO restrooms or showers. Only a portly potty with turds floating in blue fluid is the restroom accommodation. But it is the easiest marina to bike into East Hampton with sidewalks to bike upon. From any other marina you must gamble on the attention and diligence of race car drivers in their SUV's while sharing the roadway. We left early...we paid for two nights, but left after one.

Marina Response:
Hi Mantinozzi, I am sorry to hear that you ended up at a public rest room facility, located adjacent to our property. Three Mile Harbor Marina is currently completing work on a brand new club house and bathroom facility for the 2018 boating season. In addition, a beautiful new deli and market is being built over the 2017/2018 winter season, located just a short walking distance from the marina, via a safe sidewalk. Also, the Three Mile Harbor Marina Dinghy Dock is first rate, and provides a great tie up location for our transient mooring customers. A lot of exciting and new things are happening here on Three Mile Harbor. We appreciate your feedback and we will make every effort to ensure that new visitors are very clear on where our facilities are located and how to best enjoy this amazing destination located in the heart of the Hamptons. Thank you, Rick Drew Dock Master

Remote location, no answer on VHF, no immediate help to locate mooring. No access to shore either paid or otherwise. Way overpriced at $75 per night.

Marina Response:
Hi Randy, Thank you for staying with us and for your feedback regarding your recent stay on one of our transient moorings. We support transient boaters with full dockage support and related services between 9am and 5pm, 7 days a week in season. We monitor VHF channel 9 on 2 powerful base station locations and between 5 and 10 handheld VHF radios every day during operating hours. Late arrivals and Departures do require communication prior to the planned arrival and/or departure time, should you require assisstance. We do not have a launch service and the deep water mooring field is in the middle(i.e. deep water section) of Three Mile Harbor(11 feet mean low water). It is a little remote, but one of the few places that you can truly get away from it all for a special stay. Three Mile Harbor is one of the cleanest, most beautiful and protected water bodies on Eastern Long Island. We do offer three dingy dock locations (North, South and Central Harbor Locations), for Transient Mooring Customers to tie up at. We have two well stocked ships stores, fuel dock, two full service boatyards with haul outs and certified techniicans, and awesome waterfront dining at the Harbor Marina Location. Our mooring tackle is first rate and well maintained throughout the season. In appreciation of your feedback we would like to offer you a 10% discount on your next stay in Three Mile Harbor and have a chance to provide you with the 5 star service that we are well know for throughout the Hamptons boating community. Thank you, Rick Drew Dockmaster

We terminated our planned three day stay in one night as we were less than pleased with the whole setup. Distance to marina was quite far and the mooring field was isolated. No restrooms available. Advertised shuttle to town was actually the public bus going by. We asked about the dinghy dock and were told we'd have to call and check if there was room for our dinghy. I guess for the most we've ever paid for mooring fees we expect more. Its easy to say we won't be back.

Marina Response:
Hi Dstrippe, Thank you for your feedback. Three Mile Harbor is a fairly large water body, approximately 2.5 miles in length. The deepwater mooring field is located towards the center of the harbor and it does take a few minutes to dinghy in to one of our four marina properties that are located along the harbors eastern and southern shoreline. Many people like the Three Mile Harbor Mooring field because it is well protected, its deep (11ft mean low water), and offers an abundance of clean water and natural beauty. We have dinghy docks at Harbor Marina and Three Mile Harbor Marina for the use of our transient mooring customers. Each of these facilities has a well stocked ships store. Also, we do encourage first time guests to check in with us to ensure they tie up at the correct location on busy weekends. Harbor Marina has an excellent Waterfront restaurant as well. (Bay Kitchen Bar) We do not represent a shuttle to town. As you pointed out there is a public bus and numerous private cabs, car services and Uber. Our staff is available from 8:30am until 5:00pm 7 days a week in season to help with customer requests via VHF channel 9 and our main office numbers 631.324.5666 or 631.324.1320. Lastly, Three Mile Harbor Marina is building a brand new club house with new bathrooms for the 2018 season. Thank you, Rick Drew Dock Master

Very difficult to locate moorings per instruction of marina. No facilities (baths or wifi) and located very very far from dingy dock. Anchorage offers poor protection/Located in large lake (1 mi. X 2 mi.). Overpriced !!!
