Marinas & Boat Yard
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.
If you are interested in a mooring for a location within the Town of Greenwich, or if you need to renew your current mooring, you will need to complete a mooring application. You can download the application from the Greenwich Harbor Management Commission website. If you have questions, contact their office at 203-622-7713.
