One of those "Aha!" moments for me, reading that. Right. All I need is to see the depth of the water, and could not care less about the contours of the bottom nor of all the critters down there. May they swim in peace -- I will eat their kin in restaurants with great enjoyment, but they can swim underneath my boat in perfect safety. :-)
