Jack’s contracted with Dockwa to install my mooring in the spring and winterize this fall. I was billed for both in April. They are now out of that business and have subcontracted the removal. I requested a Refund and was told there will be no refunds. Don’t need this hassle!

Never got there as we were not confirmed a mooring until the day of arrival at 3:30 pm. All was not lost as the two day Maritime festival was cancelled because of the weather conditions on the east coast. Will try again next year.

It is a lovely spot but nearly impossible to find your mooring. Each mooring has several numbers, and they are difficult to see. Some type of flag or other means of marking Jack's moorings among the multitude of others would help.

We love staying at Jack’s Marina. Service is great, moorings are very well kept, we slept at 40 knots gust without worrying. Town dock is very close by. Jack’s store has great supplies for the water sports and the boat. Definitely would come back every summer.

We went in knowing that there are no services at the docks with the exception of water, so we were extremely happy with our experience. There is no electricity, no restrooms or shower. But what they do have is a gorgeous view in a very quiet corner of the harbor. We brought our bikes and enjoyed riding around the island.

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.

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

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
