Whether you are a live aboard resident or a seasonal boater, you will find no better docks in the Washington DC area. We have installed  Meeco Commodore floating docks with composite decking. These have new and certified 100 amp service with true 110/220 volts (no worry about equipment-damaging voltage drops common in many other marinas).
Individual water connections with each slip, dock boxes are available. The water is kept above freezing temperature for year round use.
