St. Leonard, Maryland · Calvert Cliffs · Chesapeake Bay
A family-owned and operated quiet harbor on the Chesapeake Bay, near Solomons Island and the Calvert Cliffs — complete marine services, storage, hauling & repair, a DIY-friendly yard, and the Ship Store.
About Us
A family-run, full-service boatyard performing all facets of boatwork. Service your own boat in our DIY yard or use our skilled crew — from haul-out to repower, Flag Harbor keeps you on the water.
Passing through? We keep three transient slips in our protected harbor — a straight shot in off the Chesapeake, a quiet night on the hook without the anchor.
More than just a boatyard — skilled mechanics on site, or use our "DIY" yard and work on your own boat with help whenever you need it.
Our specialty: ten acres of secure onshore storage above the Bay — with a DIY yard where you can store your boat and work on it right there.
