Description
This is the standard layout for this vintage.
Starting forward, there are generous upper and lower guest berths to starboard with a hanging locker.
To port is the ensuite head that has a sink, toilet, and enclosed shower. There is a second access to this head from the galley, allowing use while the sleeping quarters are occupied. Next aft to port is the galley dinette for up to six people—the house AGM batteries are under the aft seat.
The full galley is to starboard with a microwave, sink, full-size refrigerator, conventional oven, and stove top. The engine room is accessed under the steps up to the salon or by lifting four deck hatches.
The salon features cabinets and a TV to port forward, and a full inside helm and electronics panel to starboard. The salon has a full couch to port with a table, and two lounge chairs to starboard.
Next aft is down portside to the master stateroom. This generous cabin has seating to port and starboard.
The washer/dryer is enclosed on the forward bulkhead. The ensuite head features a sink, toilet, and tub with a shower.
The huge flybridge and back deck are very spacious. The foredeck has a Maxwell windlass with chain lead and 200 ft of anchor rode. The anchor is a Mantus (new in 2022). The swim platform is accessed via a ladder down from the aft deck.
Magnum Inverter: 8 AGM Batteries will run all electric (120 V) 6-8 hrs, with no generator running.
