I have read this discussion before. A waxed hull creates too much surface tension, slowing the boat down. I have heard of some folks putting small dimples in the pad area of their aluminum boats with a ball-peen hammer to break the tension. Just like how the dimples on a golf ball breaks the air tension to get it to fly farther.
I'll probably put some "dimples" in mine this weekend on Reelfoot!
That being said, I wonder why surfers wax their boards?
