Welcome to The Boatyard
at Founders Landing.

A 50-slip marina with a causal family-style atmosphere, owned and operated by the Costello Family. John A. Costello, a marine contractor from Greenport has been designing, building and maintaining boatyards and marinas for more than 50 years. He works side-by-side with his children, Jack and Jane Costello, who are both fully involved with The Boatyard. The Costello Family is deeply rooted in the local community. With salt water running through their veins, they believe in preserving the North Fork way of life and maintaining the working waterfront.


The family’s intention for The Boatyard is to provide a safe docking facility that will offer boaters necessary marine services so that they have the ability to enjoy the surrounding waterfront area. This property is a unique niche with a vast maritime history. The hope is that boat builders, marine mechanics and other maritime businesses will once again call this site home.
