When is a board SMOOTH enough?
Do you stop at 320 grit and know from experience that the board-bottom is SMOOTH enough to surf it ?
Or, did you rather take the whole process a step further and fine sand it to a 1000 Grit, after which you took out the Polisher and polished it till 10.000 grit, till you found the board to be REAL smooth.
WHAT is the difference in the skimming [surfing] properties of the surfboard with a real real smooth surface and a seemingly smooth surface?
From boat-builders in my country I heard saying that the competition sailers do not want a perfect smooth boat-bottom. For then the bottom and the water stick together better [something called adhesion ?] ==> more resistance for the boat to go through the water.
Anybody did experiments?
Bye U-all, happy writings.
