Was it the standard or the harder version of island 44? What primer did you use.
How much would i need for 2 saildrives? How long can you store that? Can i put it on the prop too, trilix you apprently can.

Is that the one you mean:

I prefer harder as i don't have very good experience with soft antiouling at all. A fishernet caught in the saildrive/prop will damage a soft antifouling...
TBT has been outlawed.

Dammed…same BS then in automotive with lead based primer, what really works is outlawed…well I found a way to still get it and use It as used for eg steel bridges or the Eifel Tower in France as no alternative. Still way to get TBT based one? Clear no workshop will do it but if applying myself nobody cares.

And micron 66 as the next close on with at least 3 years till 4 is discounted as well.
So what’s available and last 3 years minimum?
What about Colorkote? That seems sea haws top notch antifouling, they claim multi season usage.

saildrives is quite easy reachable without dive gear and I go swimming nearly every morning as my routine and taking care of one part daily eg quickly going over one saildrive remove grime.
Can I put micron 66 on propeller to, have flex-o-folds. There prop speed worked not like expected and because it’s soft you really cannot do much. Props can be reached even easier as saildrives behind rudder on Lavezzi, can fully reach them just with a snorchle. Maybe even polish them and nothing at all or a hard antifouling where you can also get some barnacles off, if in marina longer then 3 days put a plastic bag around them…

TbT paints are still legal in some third world nations. I'll let you do the legwork on where, however. There's a reason most seafaring nations have banned it.

Being an ablative paint, Micron 66 will not last long on a prop. But since it's been discontinued, you might not be able to find it even if you wanted to use it in that application.

Ahh crap...well then please tell me what works min 3 years on the saildrive and is allowed. Barefoot route so warm weather. Coppercoat with more copper works great but what on the saildrives...that defeats the whole coppercoat of i still need to haulout early, there must be something that is prooven to work and avaliable...
Colorcote?

Its the same BS then in automotive with paints...
There is a reason there is no alternative till today to lead base primer and still used worldwide on eg Golden Gate, Eiffeltower or any other public metal construction...they just ban what works and replace it with something working less good and you need more or have to recoat more often so the total endresult you gave actually more poison and more harm. But nobody looks at the total anymore...EVs nothing comes out of the non existing exhaust, so no CO2....thats why everything is ****ed up.

Re: Copper Coat on an Alu hull - yes or NO ?

How do you manage the interface between the aluminum drives and the copper on the bottom and/or the prop?

No contact whats or ever and the copper is binded by the resin to the fibreglass hull.

The problem applies when you put coppercoat with a barriercoat directly onto the aluminum saildrive and eg something swimming in the water and hits the saildrive and penertrate that barriercoat and you have direct contact from the coppercoat. Coppercoat suggests to do this but i stayed away due to reason explained here in the thread.

The only anti fouling paints that can go directly on aluminum are ablative. Good luck getting 3 years out of one of those.

Re: Copper Coat on an Alu hull - yes or NO ?

Its actually hard to find info on what aluboats have in nowadays.
The only 2 mentioned regularly are Trilux33 for low/med growth or seajet 34 for strong growth.

You've gotten all kinds of straight recommendations. But maybe you just don't want to hear them.

What recommendations? What’s mentioned is not available anymore.

But well my berth neighbor with an ovni steered my towards a German „anti fouling forum“ and a seller of commercial antifouling for commercial and military ships which also refills in smaller quantities and sells them for the leisure boat market.

The RELEST® Marine 522 AF Ecoship Antifouling from Akzo Nobel applied in 2 coats will last 3 till 4 years on the saildrives, 3 coats should get me to at least 4 Years. Well even if only 2,5years it is better then what I have now and could find till now. This antifouling maxed out the highest level of Biosides and Toxics allowed nowadays.
RELEST® Marine 522 AF Ecoship / rotbraun - schwarz
Used by German and Dutch navy as well as coast guard on their steel and aluships.
Great forum in German attached to shop and the guy is a pro and no bs talker
Forum - ANTIFOULING-BESCHICHTUNGS-FORUM FRAGEN & ANTWORTEN FRAGEN & ANTWORTEN
Loads of good info eg loads of brands selling but actually only 9 producer worldwide of antifouling paints.

I have seen it used successfully in the Caribbean. They even spray painted it thin, then buffed it for racing and it stayed clean for a year when they redid it because they do it every year.
