Sorry to interfere but it is rocket science. Hull or fin surface can vary from polished to matte to rough and there is no definitive answer about what is best (notwithstanding what "best" means). Most probably it depends on many other parameters. Nanostructured materials are an interesting breakthrough as water hardly touch them, there is no surface energy or boundary layer in the classical sense. But there are probably too expensive/fragile for windsurf.
