This a super duper International Micron AP antifouling after about 2 years . Covered with barnacles .
It's suppose to be effective in highly fouling area.
My boat was on Brisbane River .
Would not expect such a buildup of barnacles .
Not impress .


For 2 years in the Brisbane River I think you have done fairly well.
This is about 2 years in the Burnett River.

I have Micron Extra on my boat. In Geelong it was fine. Sailed to Sydney and have the boat in Balmain. I left the boat for about 6 weeks and came back to find the hull completely covered in barnacles. After cleaning off I get some green stuff within days and barnacles start coming back within a week. I antifouled in September last year.
per another recent thread i am keen to give Seahawk Biocop TF a try.
Port Hacking the hard shell grows like crazy

The growth in Sydney at the moment is crazy. It grows back as quick as you clean it off.
It is ablative so the boat has to move regularly to get best results
don't use ablative if the boat sits

Brisbane River run for about 3 - 4 knots when tide changes , it's constant water movement . Not still water .
