BBYSTWY,

Copy/pasted from another thread I just replied to:

On our model boats, particularly the outriggers and hydroplanes, we use a technique we call "crosshatching" on the sponson bottoms. We drag the bottom of the sponsons across a piece of 1000-1500 grit sandpaper on a flat surface, in both directions, on a 45DEG angle relative to the direction of travel. You really can't even feel it, other than it feels slicker than the gloss painted finish. It creates significant aeration of the wetted surface, but doesn't create any unwanted changes to hydrodynamic behavior. This can translate into several MPH and a smoother running boat. I have often wondered if it would do any good for full size boats.

Essentially, glossy is sticky.

Thanks. Brad.
