Our stay was excellent. Halsey’s is a nice marina with neat, clean and well cared for amenities. Les Black was great and could not have been nicer and more accommodating. From his guidance in entering the marina and tying up to his vast local knowledge of East Hampton, Les was exceptional. Throughout our stay he was always checking in to see if we needed anything. Les is what makes Halsey’s a 5 star marina!

Excellent Town Dock. There for 3 years

We stayed at Halseys Marina in Three Mile Harbor. Planned to stay 1 night but seas dictated that we stay another, which the marina was able to accommodate. Dock Master, Les Black is now our "Gold standard" for dock masters moving forward. He contacted us via cell phone prior to our arrival to ensure that we would have no trouble finding this small but very quaint marina. Les asked us to text him or call when we were at certain points in our journey and gave very specific directions to the marina which were spot on. Les and a deck hand were on the dock waiting for us which was a reassuring and refreshing change from what we have often experienced. In addition, Les gave us the lay of the land and made recommendations for meals and entertainment. Halsey Marina had a lovely bath house with indoor and outdoor showers and a nice TV room AND laundry machines. The barbecue area was more than sufficient and lovely, under the trees overlooking the harbor and spectacular sunset. We were later contacted via text by Les asking if we needed anything or had any questions. We will mark this as one of our favorite spots and hope to go back. Kudos to the 3 Mile Harbors team and especially Les Black.

Les Black is an excellent dockmaster. Great directions on where to go to find Halsey's marina, lovely slip, beautiful marina with lovely sunset views. Great water pressure to wash the salt off the boat, excellent facilities with 3 large commercial washers and dryers. Les gave great recommendations for dinner and where to provision. Highly recommend!

Outstanding Stay in East Hampton at Halseys Marina, Les and his team provide incredible service from start to finish. They recommended a few dinner spots and Bostwick's on the Harbor was what we chose. It is a great spot and great menu. We will be back to Halseys Marina soon! Annie and John H

Great accommodations and Les is the best. Helped us dock and helped us after hours when we pulled in. Very responsive. We will definitely be back!

There are 4 marinas owned by a common group. The dockmaster at Halseys Marina, Les, was wonderful. Gave good instructions on how to enter marina and did an excellent job when we left the slip. The dockhands were always there to help or ask if you needed anything. I highly recommend this Marina and will definitely contact them next time I plan to go to Three Mile Harbor.

Marina Response:
We're delighted to hear that you enjoyed your stay with us in Three Mile Harbor! We hope to welcome you again in the future. Happy boating!

Could not do enough for us. Attentive to our needs. Made sure we were comfortable with our location because of an elderly dog who has trouble getting off of boat. Offered suggestions on where to eat or go. Had interesting bits of info on people and places. All of this describes a super nice and generous dock master, Les Black. East Hampton has a top notch person on their team at their marinas. We stayed at Gardiner's Marina but Les also suggested Halsey's for a visit next trip.

Our moorings reservation worked perfectly although we never discovered where the Marina was or took advantage of anything other than the mooring itself. Gorgeous harbor.

by Brett S. - Verified user on Jul 21, 2022
A lovely spot, we were stern out towards a beautiful harbor with quiet boat traffic and amazing wildlife. Les and crew were ever present, very pleasant, and always helpful. Well located near restaurants, an amazing deli, and a famous farmstand. We paddle boarded all the way to the far end of 3-mile harbor, great exercise and just beautiful. In all, a great place and stay.

These guys were awesome! All parts of the experience including checking with us to make sure we got back to CT safely. I highly recommend this group (4 marinas) Les (dockmaster) is great!

We were on a mooring ball. The marina is not too far away via dinghy. A very pleasant stay and their bathroom facilities were spotless!

The harbor master, Les, is wonderful! He goes way beyond what you would expect. We love Halseys Marina, but the main reason we come back is Les!

by Jeff D. - Verified user on Sep 09, 2021
Three mile harbor is a very nice place to spend a few days. There is a good anchorage there and we would have anchored but our windlass was out of order at the time. The mooring balls are SUPER expensive and we only got one because of our windlass situation.
