The transducer was on the outside, but the prior photo is down-imaging that shoots a 170 degree beam perpendicular to the 'toon, so it will catch the fins (or anything else) that is at a right angle to the transducer. That's why if I move it back a few feet, it's not an issue. On the Assault XX, mounting the transducer by the side-bag, as you suggest, worked great.
With a 20 and 60 degree sonar cone, the fins aren't nearly as noticeable (see below), but still create some interference. Move it a few feet will solve this problem as well.
I just thought the image was an interesting (but extreme) example that you have to give some thought to transducer placement when you've got feet, fins or oars poking down in the water.
