About National Marine
All Slips have metered electrical pedestals with 30 amp service. Water is provided. Dock Boxes are included with each slip. Only dock boxes provided by National Marine will be permitted on docks. Boats that are longer than the slip must be approved by management and will be charged for any extended protrusions. If your boat is smaller than the length of the slip, the price will be based on the actual slip length. Sterndrives, outboards, swim platforms, and bow pulpits are considered in the length of the boat. Wide beam boats will be charged a flat fee. Slip renters will have use of the launch ramp at National Marine at no charge. Trailer storage is available inside and outside. Check with office for fees
