The images that follow are from a Bellingham-built 1983 Bayliner 3270
The Word document describes the hull construction technique. The opinions are from a tech with lots of experience building boat hulls with chopper guns.
The three images below show the hull where the transducer is mounted (third image). The mounting location is in the crawl space (aka "cave") just aft of the platform on which the water heater rests.
The image below shows the transducer plug from the port side of the boat. It is only slightly farther aft than the images above. The Word doc talks about this plug.
The next two images are sections of the bulkhead between the crawl space and the aft cabin bunk. They are the same. One is larger diameter.
The floor of the salon.
The salon liner. This is the gray stuff you see from the salon.
The inner hull (different from the salon liner) about midships just below the gunwale. There are two layers of hull here about an inch apart; the next image shows the outer hull.
The outer hull in the same location.
The hull at the location of the engine room side air vents. This is essentially the same as the above photo of the outer hull.
This piece came from the side of the small step in each forward corner of the cockpit.
The two images below show each side of the piece that came out when I cut a new shore power inlet opening next to the existing one.
The transom
The bulkhead between the starboard side V berth under-bunk storage and the hanging locker immediately aft.
This is from the bulkhead which runs fore and aft and separates the center section of the V berth under-bunk storage from the starboard compartment.
This is from the bulkhead at the lower forward end of the storage area on the starboard side of the salon. A vertical wire run is just forward of this bulkhead.
This is the power receptacle opening in the bulkhead between the forward part of the head and the hanging locker in the V berth area. The gray fiberglass is the head enclosure.
