Coecles Harbor Marina & Boatyard has been family owned and operated since 1973.  Over the past three generations, CHMB 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.  Our facilities are meticulously maintained; our staff  friendly and professional.  We encourage anyone and everyone to experience the CHMB difference for themselves.  From the restoration of classic wooden yachts to the fabrication of the 38' Shelter Island Runabout. We invite you to tour our facilities to  see what we do best.
