those shots were pulled from humviewer where I went into a SI left and right view and changed it to only look at the right side. I was following a channel with the sharp drop bank to my right. Nothing to the left to see and the fall downs were all to the right coming down the highwall. This is why the depth reads(IMO) more than the distance from the center line of the boat.
Hope this helps in reference to your Q. Good eye for detail
