does a waxed hull increase speed slightly

Here`s what I am wondering:
If sanding the hull reverses the effect of water adhesion, (a concept I understand and believe) then would it give you better results the bigger the hull you have?
I have a 22' Baja hull with 21* deadrise. If I sand the contact area with 1500 grit, will I actually see as much of a gain as say a person with a 29' Outlaw with a 24* hull?
With my hull, how much could I realistically expect to gain by sanding? Give me realistic numbers......

F31...yes, in some ways, but what i am getting at is with less power friction becomes a greater obstacle or hinderance, generally speaking. We are talking about the same issue, no matter the hull....how to reduce the drag/friction/negative energy of the water rubbing on the hull.
Certainly other variables, but the premise is the same...reduce friction.
I know a guy who syas he picked up 4 mph on a 31AO with big power by wet sanding the hull.
Why don't more people do this we ask??? I don;t know. My guess is appearance.
Donman...this is only a guess, but I would say you might pick up 1mph or so. Having never done this to a power boat, I do not know...an yes....I do race sailboats from time to time...

R....we sand ina circular motion in no particular direction or start/finish area.
I may try this later this year....see what happens.
