Re: Fishfinder vs depth sensor
I took out the depthsounder when I bought my Morgan 36 Out Island in 1999, and replaced it with a Humminbird "Wide 100" fishfinder.
The transducer is mounted inside the fiberglass hull (not a _cored_ hull), on a pad of silicone caulk. The silicone reduced efficiency -- I can only read bottom to 300', instead of the 600' rating of the sounder.
The fishfinder could have been mounted on the cockpit bulkhead, but I made a little plate of "Starboard" (plywood would have been fine) , mounted that on my steering pedestal, and mounted the Wide 100 readout free-standing on that.
I have no regrets. The unit has seen several thousand miles of sailing.
