Zero stars, couldn’t find the mooring, contacted the marina as requested, very nice guy tried to help. No on water help. He agreed to cancel with full refund and the general manager is supposed to contact us. We ended up getting a mooring at Shelter Island Yacht Club. Even they didn’t know where the mooring J11 was. The next morning we went with our dinghy and found the mooring with another boat on it, and the tackle and location was not suitable for our boat.

Charlie is very responsive and helpful. Beautiful harbor surrounded by incredible homes and vistas. Great location, once ashore you’re walkable to North Shore Ferry and nice restaurants. Mooring ID could be better but we finally found ours.

Great location and super friendly people trying to help out. We had trouble trying to find our mooring, the link to the marina map in the email from Dockwa was not working and it's a super confusing mooring field. We got on another mooring that was fine but a little tight for our boat length Make sure you get the marina map before you proceed in.
There is a yellow bus that seems to go around the island every 1/2 hour leaving from downtown. We should have taken that and explored the island a little. Not a tourist mecca but an excellent, quiet town that was a nice visit.
5 stars if the mooring is easy to find and has a nice comfortable swing room.

I am giving the staff who work at the hotel and answer the phone a star as they were very friendly when they answered. I am giving them one more star for initially being flexible and accommodating our one day delayed arrival.
The rest of the experience was not good. Never got a response when hailed on the VHF. Trying to find the mooring took forever as they are not well marked with the number at the bottom of the balls instead of the top. When we finally found our mooring ball, which was located next to two boats per Rian’s instructions, that were not anywhere in the field and did not exist, there was no pendant or flag pole attached to the ball. We finally just grabbed another one and there were told that we could not have that one and we needed to relocate to the next number, which had two balls with that number on it.
We connected with the yacht club in the cove and moved there and they were wonderful and worth the extra cost.
If Rian wants to improve their mooring services, they minimally need to post, even if just hand drawn, a map of the ball locations, and give them some serious TLC. The mooring ball we picked up and got moved from, we couldn’t even really make out the number when they asked.

It does not look like moorings have been maintained in years The moorings are basically impossible to find. I am still looking for my assigned mooring. There is no staff on site. The phone number that they supply connects you to the front desk of a nearby hotel who, while nice, are useless. It took an hour and something like 10 phone calls but I eventually found a reasonable mooring (not my assigned one) and picked that one up. Of course, some aggravation is worth it because Shelter Island is beautiful.

Nice location, very quiet! We were on a mooring and the dinghy dock is easy to get to. Friendly boaters.

Once I was settled on the mooring, all was good. The mooring itself had a very short line and it was a real struggle to secure my 37’ trawler. At the same time a sailboat with a much lower bow rise got a mooring with a much longer line. I think they should have a better knowledge of their moorings and assign them by boat profiles.

First time with my 29 foot powerboat . John and Tom were both great. Had a little trouble finding the mooring since mixed with the neighbor marina next door. Tom came out right away and got me to my mooring. The only hickup was that the mooring was quite short. John stepped in and corrected the situation. I had another problem which was due to my lack of knowledge of my own boat but John offered immediate help and care even after hours. GREAT Staff. I’ll enjoy going back next time I’m up with Gewn Ha Du from Hampton Virginia
Chequit hotel which are the same owners Great place to stay right next door
Casual Chic

Absolutely lovely. The man working the front desk was so extremely kind and helpful. Come here for incredible sunsets and a cute small, small town.
Ps. The mooring was easy to find- we just called a few hours before arriving and asked for directions, as one entering a new harbor should.

Nice spot in beautiful Dering Harbor. Heads up, Jack’s closes at 4. No way to get in touch with them after that. We had to hunt for our mooring. We found the mooring assignment on Dockwa and finally found J60 with our dinghy. If this happens to you it is an orange mooring in front of the private dock on the south side of the harbor. Jack’s… you should be more proactive for check ins after 4.

At Jack’s you get a mooring and a nearly new, nearly empty dinghy dock. No amenities… it is what it is. They came out in their boat when I couldn’t find my mooring… which was a short row to the dock. There’s a nice pocket park next door where you can tap into Jack’s wi-fi. Dering harbor is a delight… a nice high end specialty market right there. Liquor store, too. Walk to coffee/bagels is about a mile, as is the supermarket, but it’s part of the Shelter Island experience.

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.

Beautiful harbor and Jack`s Moorings are right at the end of the harbor near the shore which has great, easy access to the town dinghy dock... to find the J mooring go all the way down to the gas station and make a left follow the mooring balls it goes j1, j2, j3, 4, 5 etc... Shelter Island is beautiful.... Jack`s has stuff for boats if you need something.

Still waiting for a reply to messages I sent prior to my date of arrival, was not able to make the trip due to work and requested to move reservation to alternative date. Followed up twice and still no reply… I am hopeful I am not charged for the entire stay due to their lack of responsiveness.

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.

great spot. great people.

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!
