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.

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

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.

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.

It is important to understand that when laid up the Hanse epoxy boats have an exterior gelcoat layer and the epoxy layers are subsequently laid on top of the gelcoat when in the mould. This is a normal layup and the only difference as far as I can see is that epoxy is used over the gelcoat when in the mould instead of using Polyester or Vinylester resins.
The point that I am making is that from external appearances, Hanse epoxy yachts look like any other yacht because the outer shell is Gelcoat and a white Beneteau, Oyster or Swan for example should weather in a similar manner.
There are lots of benefits of using epoxy since there is no osmosis issues and epoxy is tougher and stronger than the other more commonly used (and cheaper) resins. This allows epoxy yachts to either be much stronger for a given hull thickness or just as strong with a thinner application and much lighter than a similar non epoxy hull.

You are lucky if you have an epoxy hull. Hanse does not made anymore hulls in epoxy.

I really don't understand what you are saying. When we talk about an epoxy hull that means that is a fibreglass hull, with epoxy in place of the more widely used and less expensive polyester resins.

When you use epoxy over the gelcoat is a different thing. It is called a coat and almost all manufacturers will propose that to you as an extra. That means that is a fiberglass hull made with poliester resins and on top of that you "paint" several coats of epoxy on the hull to make it really waterproof.

I don't know if you have an epoxy hull or if you have a normal poliester hull with epoxy coating. Hanse used to do as an option epoxy hulls but not anymore. If you have a 470e than you have an epoxy hull.

Thanks for the info Paulo,
Just curious why an epoxy hull construction would need another color besides white.
Would like to know the drawback of a Hanse epoxy hull with white hull color.
Thanks in advance for any input from the forum.
It seems you come too late. I have said that three years ago. They don't offer that option anymore. That option is offered now only by Dehler (that belongs to the Hanse Group) or for instance by Salona.

That is a good question, I mean the color. Hanse or Salona propose epoxy boats in white but some say that light degrades epoxy and that a colored gelcoat should be used. The problem, if exist, should not be serious, otherwise they simply would not propose epoxy boats in white. Anyway, just in case, if I had an epoxy boat I would have it colored. I almost bought a Salona and I was thinking in light grey. It is not that expensive and a light color has not the problems that dark colors have in regarding losing "shine" with the sun and age.

4arch My wife and I looked at what they had on display of the Hanse line at the Annapolis boat show. I believe we were somehow (mis)taken by the broker as serious potential buyers, which was nice because we were able to poke around on the boats quite a bit and have a lot of questions answered. We were both fairly impressed and saw the Hanse 355 and 375 as being a lot more “us” than offerings from a lot of the other production builders.
