Nestled at the mouth of the Connecticut River, our marina offers an unparalleled vista of Long Island Sound and the river itself. Situated just inside the Saybrook Breakwater, we boast swift access to the river and the sound, ensuring convenience for all our guests. At Harbor One, we take immense pride in our commitment to exceptional customer service, guaranteeing a tranquil and rejuvenating experience for seasonal and transient visitors.
Over the years, we have diligently upgraded our serene facility, expanding its capacity and implementing round-the-clock surveillance cameras to prioritize your safety. With accommodations available for boats up to 150 feet in length, our newly renovated dock house is stocked with gasoline and diesel fuel, essential boating supplies, and ice.
