I know what you mean about hard water. When I learned to barefoot, a neighbor was kind enough to offer his boat and drive for me. As soon as I stepped off the ski I did a face plant and saw stars. It turns out that the speedo picked up some weeds and didn't work, and his tach wasn't working either. He thought too fast was better than too slow, and he "thought" he might have been going around 45 mph. After a short breather I did learn to barefoot that day, albet at a slightly slower speed. I did a radar'ed 68 mph on a slalom ski once and really, really didn't want to fall at that speed! Just the spray from the boat hurts going that fast.
