About The Boathouse Marina, LLC
We are located approximately 45 nautical miles up the Potomac River from the Chesapeake Bay. On the Virginia (left) side of the River you enter Monroe Bay by passing marker 4. Further out in the River is an entrance marker #2 that guides you past a shoal area coming up to Monroe Bay. Come into Monroe Bay keeping Red Markers 4 thru 12 on your right. At Red 8 and Green 9 make a slight starboard turn and you'll see Red 10 and the marina dead ahead. There is 6+ feet of water in Monroe Bay up to The BoatHouse Marina at MLW.
