About
Greenwich Waterside Marina welcomes boats of all types and the friendly boaters who captain them. Conveniently located in the protected waters of Cos Cob Harbor, just south of the I-95 bridge, our marina accommodates vessels up to 50 feet and beyond. We offer brand-new docks equipped with both 30- and 50-amp shore power connections.
We are accepting seasonal slips for the season and you can contact us at [email protected] for more information.
