Re: Hanse Yachts

Hi Paolo

What I am saying is that when laying up the hull the boat is constructed from the outside inwards with the first step being the gelcoat being sprayed into the mould and the epoxy layers are added after, which then becomes the interior of the hull.
The point being that all fibreglass boats, epoxy or otherwise have a gelcoat layer as the external skin and the colour requirements should be identical I would have thought.
Cheers
George.

Re: Hanse Yachts

Yes, that's like that.

Even so some say that on epoxy hulls a colored hull is better for added protection to uv. Maybe the gel-coat will give it enough protection but probably it is also an epoxy gelcoat. I would not worry much, they are supposed to be UV resistant even if the epoxy has some problems with UV.

Regards

Paulo

Re: Hanse Yachts

Hi Paulo
I believe the Gelcoat on my Hanse 470e is polyester as I have repaired chips with normal polyester gelcoat, which works fine. If the Gelcoat were epoxy the polyester repairs wouldn't adhere, since you can epoxy over polyester but not the other way around.
Anyway... four and a half years after launching and the white gelcoat still looks like new in the harsh Australian sun!
Cheers
George

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.
