How about the one where Hydrophobic wax (regular 'ol wax) would make your boat float higher because it pushes water away?

I'm an enginerd and have never heard any testing that anyone performed that was objective and thorough in relation to waxy, oily, or wetsanded hull bottoms flowing through water. You can tell me until you are blue in the face that you think your boat is faster with this coating or that or that you were faster than sombody else without but it's not objective. As an example, it always seems like my truck runs better after a washing although I know it's physically impossible. Point is, personal opinion and "feel" are not adequate enough to stake a claim on some scientific result. Show me the money! Until then, I'll focus on keeping the bottom of my boat clean and fair and trying to avoid mistakes on the course.
