Osmosis on Hanse

Several of you have spoken of the recommended treatment to the hull included in your paperwork - I looked in my 'manual' and it gives no recommendations for this. I had my boat primed and antifouled by Hanse UK prior to launching but I was never told what materials were used. Does anyone know if an epoxy primer is used as standard by Hanse UK?

I understood that to give full protection to the hull you needed to apply a full epoxy system with many coats. I also read somewhere that applying this to a new hull is not a good idea as it prevents the hull from 'breathing', trapping Styrol in the lay up which can cause more trouble in the long run.

Does anyone have a view on this? 

Hi Alan,

It is correct what you are saying about serveral coatings (I believe 5). The hull must breathing in the beginning. That is what they told me also. Better to do this after a few seasons. The only thing is that the boat must be totally clean so no anti-fouling. That is a little bit extra work.

But when I became the boat (okt 2003) I painted the boat myself(anti-fouling) The only thing what I put under the antifouling was a coat that makes the anti-fouling better holds, if you know what I mean. The name is heavycoat. They say that normally every Hanse will be delivered like this. It cost around 1500 euro's and they only do this and nothing more.

For the first question I do not know an answer. But in holland they do not use standard a epoxy primer.

Hi all,

that's my I did it myself. I saw the boats at Hanse in Greifswald and I think it's not done in a proper way.

After one winter outside I put on 5x VC-Tar2 and 2x VC-17M Extra. It looks pretty good after one season baltic sea, just the prop made some problems with ? pocken ?. Even the keel looks good - beside the downside of the keel :-(

Regards Thomas.

I am sorry I have only just seen this topic on our site as I have been away on holiday. I have read all of the postings.

Osmosis is a very wide description for all kinds of gelcoat defects most of which can be treated locally and cheaply. The speed at which boats absorb water varies considerably with local conditions and temperature and all manufacturers recommend that a boat is pulled out of the water for at least 3 months every winter. People choose to ignore this advice because modern resins are much more likely to be ok if the boat is left in for several years. You will see that in other manufacturers' so called 'guarantees' they only warranty the boat if it is dried out every winter and they will only put right obvious defects - which does not include stripping off all the gelcoat.

I do not know how bad the problem with your boat is and I think the main frustration seems to be that you think Hanse in Greifswald are not willing to talk to you.

I have spoken very briefly to the yard, who told me that they have in fact been in discussion with you over a suitable course of action. They have promised to send me all the facts tomorrow and I will reply to you again on Monday.

Can you please confirm where your boat is lying, the hull number and your name. If you prefer to do this privately, then send me an e-mail to Peter 

Dear Mr Thomas,

Your willingness to help us is highly appreciated.

However, both our supplier and the current distributor already did their very best for many, many months. Until now they were not successful. Since last August we applied to Greifswald directly but are still waiting for an official reaction of them.

Hanse has all the information they need. Even their own technical man, 'Til Andras', came to investigate this matter in June and has reported to the yard. Our hullnumber is 83 and in Hanse's file, all the information should be available (some of which is sent several times).

As I said before (unlike your information) they have NOT been in discussion with us about any suitable course of action.

Regards,

Anxious Owner
