Surface prep - foil wings and masts.
Thoughts for the optimum finish for foil wings and masts for low drag?
Should wing (lift) surface prep be different from mast (no lift)?
I know it's been covered many times before re. America's Cup boats, windsurf fins etc. but are foils different?
Video below (from 7.40 on) has interesting things to say re. laminar vs turbulent flow.
