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.

All good! No launch service for those who need it.
Great Service on the moorings.
Friendly and courteous staff. Nice well run facility.
Great place to watch the Grucci fireworks show!
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.
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.
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.
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 !!!
