About Harbor One Marina
Harbor One Marina has proudly served boating customers since the early 1970’s and is affiliated with Portland Boat Works, Inc. just north on the Connecticut River. We have earned a solid reputation as being one of the area’s premier yachting centers and well-equipped marinas. In fact, due to its beautiful and convenient location, Harbor One has become a destination location for many.
