Our attentive staff is dedicated to assuring you a perfect stay. Whether choosing a GEM electric car rental, a day trip to Sunset Beach, a wine tour, a dinner at one of the island’s great restaurants, or a lazy day in the pool, we are happy to assist.


Our History

Coecles Harbor Marina & Boatyard has been family owned and operated since 1973.

Over the past three generations, Coecles Harbor has distinguished itself as a top-notch service yard and premier New England destination.

Over 40 years of family owned operations have helped us develop into the marina and boatyard that we are today. We aspire to treat all of our customers, seasonal resident or weekend visitor, as part of the family.
