Greenwich has some of the best boating waters on Long Island Sound. The Town Boating Program is in place to provide residents with affordable marine facilities which enable them to take advantage of the recreational pleasures of boating.
There are three marinas; Byram, Cos Cob, and Grass Island as well as one boat yard at Greenwich Point. All three marinas and the boat yard have landing floats and launching ramps available to use with a valid Facility Use Permit. These facilities are open April 15 through November 15 each year. Winter storage is available at all 3 marinas and the boat yard from September 1 through June 15.
We provide a host of services which meet the active boater’s needs (verification of residency required). Please be advised that some services have wait lists.
