Great Peconic Bay Marina is family owned and operated for over 35 years.

We are more than just a marina.

We are a family of boaters, just like you. Great Peconic Bay Marina has been family owned and operated since 1978. We are dedicated to giving our boaters not only a place to “refuel”, but a place to recharge and rejuvenate with family and friends on the water. Located right on the Great Peconic Bay, our facility is here to make your time on the water a memorable experience.

Open year ‘round, access to the marina is available 24/7 via our video monitored security gates. We provide a long list of marine services to keep your vessel “ship shape” and GPBM’s Certified Marine Service Technicians are on staff to handle all your mechanical needs if one should arise.

Come and enjoy our many family-friendly premium marina amenities; you can sun yourself on our sugar sandy private bay beach or bring your children to enjoy time on our playground.

There is ample parking for you and all your guests to stop in and enjoy our barbeque and picnic areas. The newly renovated restrooms with showers and private dressing areas are spotlessly clean and our fully stocked ship store has many parts and supplies to cover all your needs on-site.

Our gas dock is readily available with gasoline and diesel, plus we offer a 24-hour pump out station on site. We even have a propane exchange for your barbeque! For vacationing boaters that want to enjoy the East End of Long Island, transient dockage packages are available.

Stop in and say “Hello”, we’d love to meet you!
