Our Company
Harbor One Marina enjoys a perfect location on the Connecticut River immediately inside the Old Saybrook, CT breakwater and Bell 8. Over the years, Harbor One has made continuous enhancements to its beautiful and tranquil facility, enlarging capacity and installing 24 hour surveillance cameras for your security. The marina accommodates 86 boats up to 150 ft in length and the newly renovated dock house located on the main dock, which sells both gasoline and diesel fuel, offers basic boating supplies as well as providing a home base for SEA TOW.

Harbor One Marina is affiliated with Portland Boat Works, a full-service repair, re-powering, sales and winter storage facility. Located just east of the Arrigoni Bridge in Portland on the Connecticut River, Portland Boat Works is a full-service, NMMA-Certified facility specializing in the service, restoration and general maintenance of larger yachts. We have earned a solid reputation for being one of the area’s premier yachting centers and most reliable service dealerships for all brands.
