About Us · Maryland's Source for New & Used Boat Parts
Flag Harbor Boatyard is your trusted destination for quality new and used marine parts, boat salvage, storage, and professional marine services. Whether you're repairing a sailboat, restoring a center console, or hunting a hard-to-find part, we carry one of the area's largest selections at competitive prices, from engines and electronics to hardware, rigging, steering, pumps, propellers, hatches and thousands more. Our inventory changes every day, with new arrivals weekly.
Passing through? We keep three transient slips in our protected harbor, a straight shot in off the Chesapeake and a quiet night on the hook without the anchor.
Our experienced staff can assist with hauling, launching, mast stepping, and other boat yard services to keep your vessel ready for the water, or use our DIY yard and work on your own boat with help whenever you need it.
We offer secure boat storage with easy access and professional handling. Whether you need seasonal storage or a longer-term solution, we'll work with you to meet your needs, across ten acres above the Bay, with a DIY yard where you can work on your boat right where it sits.

"Absolute legend! Wayne was extremely helpful. I drove 13 hours to get some much-needed parts and pieces for my boat, and it was worth every mile. I will absolutely be making a yearly pilgrimage to Flag Harbor Boatyard."
"Great stop on my way up the Chesapeake. Dock master Wayne was awesome. Thank you!"
