Keyport
145' Custom DEFOE SHIPBUILDING Explorer 1945

The vessel was originally constructed of conventional Navy lighter design with a plumb stem, rounded bilge and rounded stern. During the refit, the bottom was completely replaced and a raked stem was welded to the bow, adding an additional 12 feet to the overall length and creating a collision bulkhead by incorporating original bow as bulkhead. The hull is comprised of steel plating welded to a grid work of steel stringers and frames. It is constructed with four transverse watertight bulkheads dividing the hull into a forepeak, crews quarters, guest and owner berthing, engine room and lazarette. The main deck of the vessel is provided with welded bulwarks around the perimeter. Access to the engine compartment is gained through a hatch located at the after section of the cabin. The initial superstructure consisted of a fabricated steel hard top over the mid-body cabin space. The cabin has since been extended and the pilothouse completely reconfigured.

• Bottom - Reported as 5/16" steel plating
• Sides - 5/16" steel plating
• Frames - 1/2" x 16" steel angle, spaced at 72" intervals
• Stringers (Bottom) - 3/8" x 6" steel angle iron
• Stingers (Side) - 3/8" x 8" and 12" spaced at 24" intervals
• Keel - 5/8" x 22" T stock
• Bulkheads - 5/16" steel plating welded to the hull

The superstructure consists of a fabricated steel hard top over the mind-body cabin space with access gained through hatches forward and aft. The Pilothouse is located forward on the centerline of the O2 deck and is accessed by port and starboard doors. The exterior of the pilot house is provided with controls on either wing for operation of the vessel while docking and undocking. The interior, which has been entirely reworked, will contain the vessel's navigation control stations with the helm located in the centerline. A Captain's lounge is been configured aft of the pilothouse which has been provided with Iroko paneling and fitted with safety glass windows.

The exterior of the cabin is comprised of painted steel where the interior, like the pilothouse, is undergoing refurbishment. The cabin is comprised of an upper level main saloon with a galley/small food preparation area, laundry located to starboard and a head and small bar to port from which the pilothouse is accessed via a spiral staircase. The salon is located forward in which a small fireplace has been installed. The side walls have been provided with Iroko wainscoting and the bar has been installed. A small laundry and food storage area is provided forward in which a washer/dryer and freezers have been installed. Access to the lower staterooms in the form of a steel spiral staircase. The interior is provided with safety glass panels on both sides.

• Sides - Both sides of the cabin have safety glass windows seated in stainless steel frames. The windows are all well bedded.

The engine room is accessible from the fantail through a catwalk installed beneath the stack in which all exhausts pass. The area is provided with a hydraulic oil tank and diesel fuel day tank. The engine room has been suitably laid out, is well lit and provides good access to all engines, auxiliary equipment and electrical panel board. A small utility room had been provided aft of the engine room which contains much of the steering apparatus and spare parts. A watertight door is installed through the bulkhead for access to the steering quadrant. With the exception of the battery installations, the engine room is complete although some additional upgrades may be necessary in future maintenance periods.
