I agree that adding weight to the platform to compensate for a crew too light is a dumb idea. It's better to give them lead weight to carry so it helps the righting moment. Until the crew goes overboard...
But that's not what Wayne proposed. He asked for more sail area to compensate for his weight instead. Fat (no pun intended) chance

Wayne and I are in the same weight range, I'm 93kgs. For the record we both know *where* to place our weight on our boats.
