Nice harbor. Ferry to Greenport and a nice fuel dock were highlights.

The moorings were great , Ryan, Noah and Steve were very helpful and pleasant. Just wish they had shower, bathroom and blocks of ice. However we are eager to return. Thanks for your service

Such a lovely spot! Quiet harbor with gorgeous sunrise and sunset views. Jacks were responsive and helpful with all of our questions. Moorings are a bit difficult to find as they’re interspersed with Shelter Island moorings but you can certainly find if you motor around and follow the map they’ll text you. Dinghy dock is with others, just look for the large US flag on the wall and it’s the two floating docks right in front. They offer their marine store toilet (8am-6pm) or there is a modern Portland loo (did not know this was a thing) right next door open to the public. No showers or other amenities. Very dog friendly area. East walk to the ferry to spend the day over at Greenport or just wander the (very) small town nearby.

Beautiful harbor mooring with easy walking distance to ferry to Greenport. Noah @ Jacks was great communicator and helped us find right ball. Note that you need to use dinghy docks next to marina building/cove (town or Jacks) as the one by fuel tanks is different marina use. Great location, setting, price and service. ~Pretty Tied Up

Easy to navigate and relaxing weekend!

Quiet little harbor, many years ago we would anchor but they have filled it up with mornings. It does rock a bit with the boats going by between Shelter and Greenport. Supplies close by and lots of options for restaurants. Jacks has no facilities.

Only issue was boat traffic waves with boats going by Greenport ,luckily calmed down at night for great sleep. It would be great if authorities had a no wake zone requirement for boats passing Dering Harbor

Such a beautiful quiet harbor. Easy access to SI and Greenport. Most gorgeous sunset around. Mike is helpful friendly and patient. Highly recommend.

We received a text with a picture of a hand drawn map showing the location of our mooring. It was not to scale and difficult to follow. All of the moorings had 2 sets of numbers on them. Took quite a while to finally find our mooring. (Saw others having trouble too) No heads or showers. Otherwise it was fine.

Big fans of Jack’s and Dering Harbor. Convenient new dinghy dock in town. Fabulous little well stocked grocery with great prepared food and pastry, liquor store, fuel dock, hardware store with marine supplies. Beautiful, protected and mostly very quiet. And reasonably priced, too
