Thanks for your reply, RoyL It seems that when fluid flows gently, then turbulance is not a problem and skin friction can be significant. Therefore coating the hull with polish would be an advantage. At higher speed, turbulence is significant and a textured mat finish would reduce drag by increasing...

Should the surface be easily wetted as if washed with soap or should it be unwetable as if polished with wax? I have noticed that although the exhaust manifold of some cars is polished to a mirror finish, the inlet manifold was given a smooth matt finish. I understood that the mirror finish was to p...
