ummm... I don't see how a coating is going to make it more stable or corner better.... I can see the loss in top end but the other two....:bsflag:

Maybe the rough coating adds surface area to the bottom of the ski? I know it's a stretch, but maybe????

Like my truck. .
Probably like how my truck runs so much better when it comes back from the car wash. . .

The rough texture helps to grab the water better in the corners. I know it sounds hard to believe, but I am telling yall the truth.

The rough texture is supposed to reduce surface tension. R/C boats will go faster if you rough up the bottom of them.

Thats what racers do.
The hull is trued with 80 grit and the roughness creates micro air bubbles and will make you go faster cause your reducing friction and Basically riding on a thin cushion of air.
I do know that a scratched up ski bottom does handle better somewhat than a perfectly smooth glossy one though...

Like a golf ball, texture the surface to bring the object from the turbulant fluid region to the laminar region.
Not sure at what velocity a watercraft hull would enter the critcal reynolds number but if it was in or near the transition region, this could help it.
By increasing the friction factor, which is inversaly perportionate to velocity squared, you affect the reynolds number. so at a given speed, and at a givin friction factor, you can effectivly bring an object into the laminer region.
All this can be determined using a moody diagram and knowledge of some basic fluid dynamic principals.
I don't want to run the numbers to see if it works or not. Have fun

Ya, that's what I was trying to say. Add some reynolds to it and multiply that by the moody by rubbing your laminar region on it and that will reciprocate the velociraptor which is inversely proportional to the sum of the square of the hydrodynamic fluidity of the reciprocating dingle arm.
Just putting it in layman's terms...

OOOHHH!!!! Since you put it that way, now I understand.:laugh2:

Oh, I was expecting it to be black. Mind if I ask how much it cost?
And, that side shot, where it is showing some lines, was that because your paint was chipping off, or is that from the coating process?

The guy charged me $300 to do it and as far as the line goes, that is just the process. When they put it on, they took all the gel coat off and layed it on top of the bar fiberglass.
This stuff is so strong, they will go after it with a sled hammer on a boat and it will not brake or crake. They guarantee this for life or they will fix it for free. This stuff is great way to fix a hole or a crack in a ski.

Sounds like a good option for reinforcing the bottom instead of glassing the inside if it really is as strong as you say.
I'd be curious how much weight that added to the boat.

8-10 lbs.
If no one else is a believer I am. My dad's buddy has a 28ft fountain boat with a built 502. long story short they told him he was dumb and he did it anyway and lost 2 mph top speed. To me, thats a lot on a 28ft boat.
is there only one place that does this or can any body shop do it
