A few years back, I was pulling my buddy through the course in a 1999 Malibu Sunsetter and "coaching" at the same time. (yea, I know, stupid). I got too close to a guide ball and the ball passed under the left edge of the boat. For reasons that I have never sorted out, the stern jumped out of the water, the boat took an immediate hard right and the bow fully submarined at 34mph. A massive wave crashed over the window and dang near washed me out of the boat before I could yank the throttle. Scared the crap out of me and the skier (who owned the boat). We wore the kill switch for the next few weeks, but the memory faded.
