I needed a mount for it that I could remove so that the plotter won't get stolen when she's on the trailer. I decided I could make a mount like Simeon has on B3 for Noddy, but on B4.
If I move if aft, I'm a bit worried that the sun will wash it out sometimes, but it should work fine.
I started with some doubled up scrap I had left over from a sole hatch.

I 1/8" roundovered the edges and got it ready to epoxy.
Then I mounted those pieces on the backerboard and put a layer of fiberglass to thicken it out so it was a bit wider than the 6mm bulkhead.

Then I glued on the front piece.
|Glued up. Note the tape wrapped piece of 6mm plywood to keep separation.|
|Here it is dry-fit in place.|
|amidships side. You can see the pin hole through the dual layers at left.|
I've also drilled some holes for the wiring. Unfortunately, I don't have any idea where I can mount the HDI skimmer transducer. I could mount it on the transom, but I don't want to run those wires. I'll test it first and see if it will shoot through the hull. Supposedly you can't sonar through a wooden hull.
