Seasonal Slips

We invite you to check out our Connecticut Marina, which is located in a quiet residential area minutes from Long Island Sound in Central, CT. It is secluded from industrial and commercial traffic and located on the quaint Hammonasset River in Clinton Harbor, just north of Hammonasset State Park. We are a family owned and operated business that has been in operation for over 50 years!
