On a calm Bonaire day with only a few inches of wave height, I encountered the final 6 inch "cliff" at the surf line. To exit, it seemed best to move left, then forward up and out of 5-6 inches of water. Simple, right? I moved my left foot laterally expecting to put my weight on it, then step onto my right foot that would be placed on rock out of the water. But it did not happen. I had already committed my weight to standing on my left foot as I slid it laterally. After moving only a few inches leftward, my foot encountered a submerged, unseen rock. My head, shoulders and upper tank had already passed the point of no return and, in slow motion, plop! down I went. At which point, I was battered mercilessly, in slow motion, by the ocean's ceaseless, mighty-mite 5-6 inch wave action that gently pushed me around, belly up on my tank. I could squirm, but not get up. I felt very stupid in 6 inches of water and was about to take off my BC when a young guy who was watching from the hood of his pickup took pity on me. He pulled me upright. That's my embarrassing moment. I am sure it will not be the last.
