About


Greenwich Waterside Marina welcomes boats of all types and the friendly boaters who captain them. We are conveniently located in the protected waters of Cos Cob Harbor in Greenwich, Connecticut, just south of the I-95 bridge. Our marina accommodates vessels up to 80 feet and beyond. We offer brand-new docks equipped with both 30- and 50-amp shore power connections.

Local Highlights & Proximity: Our prime location in the charming village of Cos Cob offers the perfect balance of a nautical respite with easy access to town. We are just a 4-minute train ride or a 7-minute drive from the world-class shopping, galleries, and cultural landmarks of Downtown Greenwich and Greenwich Avenue. Local favorites like the Bruce Museum and the historic Bush-Holley House are only minutes away.

Dining & Essentials: Boaters can enjoy a diverse culinary scene within walking distance or a short ride. Local staples include:

-Eastend: A contemporary, upscale favorite for New American dishes and creative craft cocktails with a vibrant social atmosphere. - Happy Monkey: A fun-loving Latin-inspired restaurant from world-renowned Chef Jean-George Vongerichten. - Le Fat Poodle: A chic, bustling bistro in the heart of Old Greenwich known for its fantastic food and high-energy vibe.

We are now accepting seasonal slip applications for Summer 2026. Additionally, please inquire by email about our long-term slips or indoor winter storage options to keep your vessel protected year-round.
