Sorry, but you can't do it. You don't need to drown yourself to prove
it. You can't do it at 4.5 knots unless that's your SOG and there is
about a 3 knot or better current flowing with you and the boat.

Bill, all you have to do is kick your legs behind you and get your body up a
bit. I'll show you this summer. I can actually do it at faster than 4.5 knots.
