The bottom of my 37' express looks almost identical to that. On this boat I have relegated to waiting on the pair with fairing blocks and doing it correctly. On my 46' sportfish it has a perfect V all the way to the keel. This boat I will be putting a single thru hull in on the keel with some re-inforced glasswork to build the transducer into the center of the V. This work will be happening right after the bluefin season closes in NC.
Thanks Gstang, Next I am going to measure the width of my small keel. If its >= 2". I may try to install there and build up fiberglass if needed, back enough not to be hit with the trailer cross members for launch and haul.
Keel is 2.25" I am going to ask my marina guys to see how far the cross beam on the trailer comes back. If it's ok I will cut out a slot to mount the transducer in the keel. I am thinking one would be much better than two. No fairing needed and only one more hole in hull. At this point I will be running 4 transducers...yikes.
1.) One Chirp B275
2.) One 3D
3.) This side scan one
4.) I have a 1150 that I will run a 2kw 28 hrtz for deep water.
I also have a B164 that is not getting used. I may try and connect that one also.
Deep Blue, I am debating mounting two different ways.
#1 out the bottom of the keel fully exposed (more susceptible to damage) possible cleaner waterflow?
#2 recessed into the keel (protected) would this cause more bubbling?, as I need to keep the sides exposed 180*? Not sure how smooth it would be too.
Because you have other transducers on both sides of your vessel, including engine inlets, this is where I would recommend placing the Side-Scan Transducer:
