Default backup system -- exactly!

That's exactly right. There is a lesson here for all boaters, and that is really the intent of the so-called "criticism" and hypothesizing. All boaters need to understand that when they are navigating at night on Lake Winnipesaukee, they are already in a SERIOUS condition that demands total attention of the captain. If you don't know exactly where you are, you should be at headway speed. Headway speed does not cause the damage shown, but I'm not speculating it was over 25 mph either. As far as navigation is concerned, you need to employ backup systems. The depth sounder, chart, eyes, spotlights, ears, and GPS all complement each other. In aviation, you don't rely on one instrument, but correlate all other indicators where possible. If you are heading across a certain area of the broads and expect 80' depth and the bottom is rising rapidly, cut the throttle until you figure out what's going on.

Let's all learn something from this mishap.
