Copper based anti fouling-warranty problem

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I just heard from the norwegian dealer that copper based anti-fouling
is not recommended on Hanse epoxy boats, and he claimed that vc17 (from
International) was one of the banned products. The hull warranty will
not be valied if a copper based anti-fouling has been used.

This sounds strange. Has anyone heard this before, and can anyone
confirm that there is an issue with epoxy boats and copperbased
antifouling in general and vc17m in particular?

	Hi Towed, Yes I did. Hanse dealer received advise about that. I had discussion regarding my 430 and it is very clear that copper based anti-fouling are banned. There are some threads about it in the the forum data base. Watch also for the Hanse 371 Megawatt story. Alain

	Hi I would think that this is VERY clear stated in the user manual for the boat? If not the dealer have a very veak case! But I gues it does't mention this, as this manuel is very limited. If you compare it to i.e a manual for a cell phone that costs 100$, they have the first 10 pages of the manual with warnings and what you can not use the phone for!

	Err, are you/they referring to the CopperBot / CopperCoat type products? i.e. a thin layer of epoxy applied to the hull and then copper granules blasted into it? Mine, like several others, was recommended by Hanse UK and done by them prior to launch - Are they now saying this is unsafe?? You have me worried... David 461#028

	Hi, From memory, I think there was something in the Megawatt report re copper antifouling and the reactions with the rudder stocks (alloy). Peter Edited by Pea Soup Crew - 31 May 2007 at 19:45

	Hi. Peter you are correct. Copper based antifouling and aluminium rudders do not mix. This will be a big problem. Regards Mike

	Hi Guys, Following was a reply received direct from Hanse when I queried this thru my dealer. The problem is only where there is aluminium such as the saildrive and the rudder stock. This reply should reassure anyone who was worried about their warranty. Cheers, John The rudder shaft and the complete saildrive must be free from copper base antifouling. That’s all.

	Here is a picture of my boat just before re-launching two months ago. Is this a problem? What does "no paint on rudderstock" mean? Is that bit of paint going to cause a problem? Arrhh. What do I do now? Haul the boat out? Why the f... doesn't the manual say that. Or did I miss it?

	Hi Colin, Afraid you have to remove the copper based antifouling from the rudder stock. Best long term solution is to use aluminium compatible antifouling in a patch around the rudder stock in the same way as is done on and around the sail drive. If you had the antifouling done professionally, talk to the contractor. They should know better than to put copper product on aluminium, and may be prepared to help out with fixing the problem. Good luck. John

	This is truly concerning and I'll be following it up with Peter and the crew in the UK. This is becoming a common theme lately. The factory is increasing destroying what was a great reputation. The ironic thing for me is that my 470 was factory coated in copper coat. While this provides me with a level of confidence that i would be able to take them to the cleaners if a claim was necessary, I'm loosing confidence that the fouling was correctly applied by the factory due to their recent lack of attention to detail. Which as we all know is no help while in heavy seas or crossing an ocean. Funny when i first joined this forum when looking to buy a Hanse there was a rogue member crowing about Bavaria's saying Hanses were below average. Now i don't and will never crow about Bavaria's (bless their plastic hulls!!) but perhaps he knew something about the direction of the Hanse business. Please someone tell me I'm wrong. Can we ask for a definitive comment from the factory on this topic, if not god help them, this site will cease to be a sales tool Edited by Brad McMaster - 06 June 2007 at 10:40
