Pool was great, lots of 😁 fun

Heading back from trips out east, we've been putting in at Cedar Island Marina for over 26 years. It's a clean facility with great docks, a pool and restaurants within walking distance. . What makes it really special is the dock master Marc (who's been there since we can remember), and his well-managed staff. Professional, welcoming, Marc runs a great marina. We'll be back!

My family has been a member for about seven years. We have been most impressed with the dockmaster and his staff. We are now understanding that the role of the dockmaster, Marc Tardiff, is at the heart of this marina. Thank you, Marc, for your dedicated service, knowledge and genuine care and concern for the members of Cedar Island Marina!

Amazing 4th of July weekend at Cedar Island Marina. Live music by the pool, and very dog friendly- our pup made a friend at their little dog park. Great location, super clean and nice showers/bathrooms, and the staff is very friendly and welcoming. We'll return for sure.

Look, I’m reviewing this marina as a guest and my experiences today. My buddy rents boats here and I tagged along with my Gkid in tow. I ended up taking out the main gate after following my buddy’s car and mistakenly thinking the kid at the gate was also waving me through as well. After the gate comes down on my car, I see the warning sign that states the gate comes down after each car goes through! Well, damn! The kid then tells me he was waving at me to stop. Not his fault as his additional jobs with the boat rental company is to let renters (and their guests) into the restricted area and to open the bathrooms near the front entrance when they call him via phone. Then he has to rush back to the docks where there are 8-9 other boats he has to service for other renters. They need to come up with a better system imo as it’s a lot for one person. And why not issue key fobs for the bathroom and entrance gate so the staff doesn’t have to stop what they are doing with the boats and personally drive their car to let you in or go to the bathroom. At least the bathrooms were clean and stocked. 5 Stars for the hard working boat rental crew and 4 Stars for the unnecessary staff runaround.

I stopped at the fuel dock. The service was great! The young lady who helped us out was very polite and knowledgeable about the water and the area! It was about 100° out that day, but she remained happy and helpful. Only thing I did not like was the price of oil. It was $55 dollars for a gallon, which doesn't even cost me $30 at other locations. I would've bought 3 gallons but not at that rate! Overall though it's a beautiful marina and is very conveniently located just inside Clinton harbor.

Awesome place. Gorgeous, clean well-kept marina facility's. On the yard side of it, very well kept, well maintained equipment and a knowledgeable, experienced, friendly crew always willing to talk to you and lend a hand. One of the largest, most well stocked ship stores I've ever seen at a marina. Great people and experience all the way around.

The world is a better place because of the owners and staff at Cedar Island Marina. We were transients, scheduled to stay one night at the marina to continue our journey home to FL. During the night my wife fell inside our boat and seriously injured herself. The staff and owners at the marina loaned us their car for a few hours, helped us find a hospital and allowed us to stay as long as needed for her recovery. We ended up being there for 3 Weeks while they were closing the marina! They never hesitated in letting us stay and made us feel like family! Michelle is the greatest! She helped us with everything, mail, supplies, advice, and kindness when needed the most. We needed work done to the boat and we used their staff to coordinate. The work was first rate and we could not be happier. The marina is clean, walking distance to shops, bars and restaurants. The marine store is well stocked and had most of the parts I needed in stock and if not they could order them. We will be back as they turned a horrible situation into a true testament of kindness and professionalism that made us loyal clients for life. Thank you Mr. Shapiro and staff! You have proved that the world can be a great place!

Cedar Island Marina is the best! They’re family owned and operated- a rarity these days- and take quality care of their customers & premises. You can’t beat the live music at the pool with recently updated cabanas and deck space! Long Island Sound’s best family marina, hands down!
