About Blue Water Marina

We are located on Grand Island, one of the largest fresh water islands in the world, half way between Buffalo and Niagara Falls, in Western New York.

Grand Island is nestled in the mighty Niagara River, upstream from one of the most visited and exciting wonders of the world, "Niagara Falls".

Blue Water Marina has been in existence since 1979 when the Stedman family, headed by Thomas Stedman, purchased the assets of Blue Water Construction, a company specializing in marine construction and converted it to the marina that it is today, managed by Daniel Stedman, Thomas's only son.

Blue Water Marina takes pride in being a full service marina, offering the best service department that is second to none. We offer complete satisfaction and quality work with the best mechanics in the area and our work is guaranteed!
