I know that the golf ball analogy is going to be used, but it's not applicable in a strict sense. Tripping the boundary layer on a golf ball reduces the drag on a sphere moving through air, by allowing a smaller ''wake'' behind the ball. On a planing surface the effect is a little different. Any planing surface is going to have transition points between laminar (no boundary layer) and turbulent flow. We are just tripping the boundary as soon as possible. All our feedback from testing and initial customer reports indicates it's working.
As usual, we're not going to do any big claims. We'll just let the surfboards do the talking.

Ever pick up a board thats only been glassed and not hotcoated? They are pretty fragile.

I’m just taking a stab in the dark here, but I’m guessing that in the last stage of the glassing schedule the Coil guy’s are using a textured vac bag, which rather than dimples has little bumps all over the inside of it. Flip the switch, suck all the air out and the bumps get pressed into the still wet resin. Remove from the bag when it’s cured and the repeat on the other side. I’m guessing that they’re not even sanding the boards much once they pull them out of the bag for the last time, just some rough edges here and there.
Like I said, pure conjecture, I have no idea really.
Hey DPSUP, the dimples aren’t really round are they? More elliptical, right?

DawnPatrol, so what was Mike Daniels saying? They're not using golf ball style dimples but didn't say what they are using.
