Apparrently you dont want the bottom surface slick..you want to roughen it up with sand paper
This quoted by hoss:
Sanding the "patch" is always good for speed. But this speed is very minimal on these hulls and best left for speed junkies trying for the GPS bragging rights. ANYONE else,,,dont do it.
Air bubbles created (airation) from a non smooth surface helps un -wetten the hull reducing drag. Drag in this case for common knowledge would be considerred as friction or in marine applications,,,,,yes even vacuum or suction in certain "hook" designs. But this all pertains to speed and where the hulls life is spent in the water. In this case the hull does not spend any life in the water. Rather just the last aft midpoint. On bass boats it was/is a delta pad. But that is a different drive system. This is a jet,,,jets love water. Not air.
Basically sand behind jet,,,NOT in front of intake. By the way front to back is bs for this operation. Circular ,like a DA, is best. Its a random pattern and go medium. 400 grit is perfect. Thats inner chine, chine to chine, and up to intake front. There you have it.
You will also lose some stability. So if`n you ain`t riding glass,,,all the time,,,it ain`t for you. Period

ABBOTT played with that stuff, or something similar, a few years back and reported gains, but it tends to wear off rather quickly

I guess that going 70 on a jet ski would wear it off 10 times faster than on a sailboat going 7 mph... Ron
