The staff at Jacks Marine are the best. Noah and Johnny go out of their way to provide excellent customer service. Need tender service to bring all your goodies to your boat? They have it covered. Have a problem with your boat, they know the right people to put you in touch with.

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!

Not a marine store anymore. I miss the expertise.

by Brent W. - Verified user on Sep 26, 2023
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.

Noah was super helpful finding our mooring!

Great spot! We enjoyed it! Jacks marine store was so helpful! Green port was a dinghy ride away! The restaurant Salt was excellent and the Shipwreck was a great outside bar with music! Definitely would come back!!

Great, little quiet harbor!

by Charles H. - Verified user on Aug 21, 2023
Very friendly and helpful. Arriving late can be an issue since they close at 5pm and it is unclear what their organization is. Nonethe les, a pleasure.

Great place, very helpful crew. Great location

by Gary A. - Verified user on Aug 03, 2023
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.

by Donald S. - Verified user on Aug 01, 2023
Great location. Great mooring. But, getting directions to the mooring was very unorganized.

by David O. - Verified user on Aug 01, 2023
Very easy, island is relaxed atmosphere

by Robert C. - Verified user on Jul 31, 2023
Great location and good services. Mooring field is tight for a boat our size. Difficult to locate our assigned mooring. Staff did come out to assist.

by Mia B. - Verified user on Jul 28, 2023
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.

Another great experience @ mooring. Great location, setting, price and service. ~Pretty Tied Up

This is a wonderful, cozy bay. Noah provided launch service during store business hours, which is very convenient. Thanks again, we’ll definitely come back!

We alway love coming to Dering Harbor it is calm peaceful and quiet.

by Tracy M. - Verified user on Sep 25, 2022
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.

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

by Vicki G. - Verified user on Sep 12, 2022
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.

Easy to navigate and relaxing weekend!

by Amy L. - Verified user on May 30, 2022
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.

by edward h. - Verified user on Sep 06, 2021
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

by James C. - Verified user on Aug 29, 2021
Such a beautiful quiet harbor. Easy access to SI and Greenport. Most gorgeous sunset around. Mike is helpful friendly and patient. Highly recommend.

by Rob W. - Verified user on Aug 29, 2021
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
