: I go back to sailboat racing experience, generally find that a slightly
: roughened surface, actually like a mat painted surface, tends to have
: slightly less drag than a polished one. Usually obtained by sanding with
: like 320 - 400 grit sanded wet.

: Dolphins also have a odd skin that gives to allow better flow, impossible to
: duplicate though.

Bill, when i run my fingers over a smooth high gloss finish it feels a bit "grabbier" than a surface that has been sanded with fine grit wet n'dry like you mentioned. I can't suport it with any science though.
