Re: Hanse Yachts
yes, it is quite as George is saying. Epoxy-based gelcoat wouldn't be sufficient UV resistant. There is no real issus with "normal" polyester gelcoat, on which epoxy + glass is used.
Then there has been a rumor on Hanse epoxy delivered only in none-white. Probably a marketing thing from Hanse - most epoxy Hanse I see are colored in some pale way.
