Re: Antifouling / Bottompaint


I like Micron 66 because it reacts with saltwater to release biocide and is microscopically ablative. I think all of the Micron series is a hard paint that is microscopically ablative, each with different release systems. In the tropics, we needed this sort of protection. 

There is no ablative action with Coppercoat. And in the tropics, people with Coppercoat were cleaning their hulls every month or two.

Everyone needs to be aware that there are the best solutions for different areas. 

Also, the SeaJet 033 that Amel was recently using (I had not heard they switched to Coppercoat) is difficult to find in areas that do not use Europe as the supply chain.

Lastly, I had Micron 66 put on our SM in New Zealand and someone I know had Coppercoat done at the same time. Nine months later when we docked side-by-side in Singapore his hull had about 1" of marine growth on the hull because he had not cleaned it, our SM was perfectly clean.

If you don't mind cleaning your hull Coppercoat might be the best thing for certain cruising areas.

When I bought my boat in 2016, Amel was using Seajet paint which worked ok in the Med but I had to clean it every couple of months and I repainted every winter. I then replaced it with international Micron 350 in 2019.  The Micron I never cleaned during the season because the International support told me to trust the self polishing and any additional cleaning would just reduce the thickness of the paint. The experience with that has been good - I never saw any reduction in speed from a dirty bottom.  One reason could be that I’m now in the Atlantic and the water is colder than in the Med.  interestingly, Amel now installs Copperplate as standard.   I am considering that for next season. There is another thread on that on this forum.
