Our peaceful setting at the mouth of the Connecticut River offers an  exceptional view of Long Island Sound and the River. Our location is immediately inside the Saybrook Breakwater, therefore offers quick access to the River and the Sound. We take pride in our excellent customer service and look forward to providing a relaxing experience whether seasonal or transient.

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 boats up to 150 ft in length. The newly renovated dock house sells both gasoline and diesel fuel, ice and basic boating supplies.

Due to our perfect location, the marina provides breathtaking vistas of landscape, seascape and waterfowl. The marina is equipped with a pool and a charming gazebo located on the breakwater to South Cove. Those lounging by the pool enjoy the best of cooling Long Island breezes and shoreline sunshine. The pool house contains laundry facilities, showers, lavatories and dressing areas.
