We pride ourselves on your satisfaction and we have many accolades, achievements and testimonials that demonstrate where we place our priority. Whether you’re looking for a new boat or a pre-owned boat, marine services of any kind, parts, accessories or supplies, a boat slip or storage, bait and tackle or spot to get you into the water and fueled-up for the day, Tri-State Marine is your destination for all of your boating experience needs. 

You can find us in nearby Deale, Maryland — only a short trip from Washington, D.C. Baltimore, Annapolis, Severna Park, Kent Island and Northern Virginia.
