Comments sound like the Government rolling out “Experts” and “Professors “ of this that and the other.... take it all with a pinch of salt...
By your own admission it is not as simple as antifouling GRP. You make the point that it needs to be carried out in a specific way and because of that you engaged a specialist contractor. There seems to be a failure of the antifouling adhesion and it is not unreasonable that you should seek recompense from the contractor if they are responsible for the failure. Similarly with the anodes if they failed to follow your instructions.The painting on the aluminium looked OK (finger crossed!) it’s the antifouling that’s failing and that would be the same on a GRP boat!
There are two sides to any story that should not prevent me telling my side of it.
The antifouling is not a specialised or complicated process and would be the same on any GRP boat so I didn’t feel I needed to complicate the story as it was not material to what I was complaining about - I would not even be complaining if the paint was failing and HYS had been making some effort to communicate and rectify the issue, if they had offered to lift us out and patch the paint up I would not have been on this site discussing it now.
Has anyone else had experience with Hamble Yacht Services, we have been shocked by just how bad their work and service has been.
We had the hull stripped right back and primed / antifouled. The original work seemed to have been carried out by untrained and unsupervised “staff” painting around the old anodes rather than removing them, the antifouling was so thin after "2 coats" you could still see primer. Now after the Covid19 lockdown we got back the boat to find large areas of antifouling falling off after 5 months in the water.
After ignoring my emails for weeks, I received and email stating that it was not unreasonable to expect the antifouling to be falling off and perhaps I should abrade the primer before I repaint it! Since then, my emails and phone calls have been ignored.
I would strongly suggest using anyone except Hamble Yacht Services for any work, there communication stops after the final payment and they are not interested in putting right any mistakes caused by poor workmanship and no supervision of their employees.
We have an aluminium hull, the hull was sand blasted and painted with epoxy primer to protect it from corrosion. The anodes were worn out and had damaged the paint underneath them.
We are more concerned about protecting the hull from corrosion than saving a worn out anode.
HYS were paid to repaint the whole hull, I had removed everything I could but couldn't reach the last few (the anodes are only about 60mm x 50mm and 8mm thick when new, after 12 months there wasn't much left.
Oh Dear .... like many stories ... as the story unfolds over more and more posts and info - the overall complaint starts to get greyer and greyer ...
Seems to me as a general lack of real communication and co-operation between contractor and contractee ... sorry to be blunt.
Indeed - If the thread title was "Antifouling issues with aluminium hull" the whole tone and direction could have been so different.
There is a lot of guesswork going on here (generally), but it is fair to say that blasting and painting an aluminium hull is more complex than GRP and less tolerant of errors. We don't know whether the failure of adhesion is due to incompatibility of coatings or inappropriate application (temperature, time between coats, preparation etc,); nor whether the way the anodes were treated is wrong and what the consequences might be. I suspect that the OP does not know either, other than small patches of Trilux are coming off after a relatively short period and the contractor has not given a satisfactory explanation.What is the difference between antifouling a freshly blasted and primed ally boat and a freshly blasted and primed GRP boat ? In both cases, is it not the case that the antifoul is going onto the primer ? What is the relevance of the material underneath the primer ?
I agree. it's not as though HYS are some provincial mob used to dealing with dories. You should be able to trust they know what they're doing.If one was contracting a specialist to do a specialist job, is it not reasonable that the specialist would know how to do the job, without the owner giving detailed instructions ?
I would have thought that a professional body taking on the blasting, repainting and antifouling of a aluminium yacht would know that the anodes needed to be remove prior to painting. The rest of the complaint by the OP appears to centre on the flaking antifoul. I don't see where there is any relevance to the material used in the hull build when it comes to this. Once the hull has been blasted and epoxied/primed (in accordance with the procedures for the hull material) the application of antifoul is surely the same ? If the antifoul is flaking off, then something was done incorrectly. The most likely thing would be that the primer was left too long before the antifoul was applied.
I do agree with some of the comments that the OP should have revealed the full story in post #1, we should have been aware that it was an ally hull and that it had been blasted and primed, but that doesn't change the fact that the antifoul shouldn't be flaking off. I also think the OP should post more of the pictures that he has, to show the full extent of the problem.
With the evidence at hand i couldn't comment on the competence of the contractor, but i'd certainly question not removing the anodes.
I think that some of the comments to the OP are unappropriated. For instance, i don't think it at all reasonable to expect the boat owner to keep visiting the yard and supervise the contractors, one would expect that they knew more about the process than the owner.
