I'm getting ready to repaint the hull bottom on Abacus. Abacus is in the Florida Keys in the water year round. Tons of slime in the area.

I'm looking at the following paints:
--West Marine brand PCA with Irgarol 30% copper $140/gallon
--Pettit Ultima SR with Ciba Irgarol 60% copper $180/gallon
--Interlux Micron Extra with Biolux 39% copper $185/gallon

Is the high copper content that important on an ablative?

Has anyone read the latest practical Sailor review of bottom paints? What was the best performing ablative paint WITH slime blockers.

I've been really happy with Trinidad SR. That's not an ablative paint, of course, but here in the Chesapeake it keeps the slime off.

Albert,

I'm also on the Florida coast, near Port Canaveral. I'm an avid follower of Practical Sailor, and have had excellent results from Interlux Micron Extra with Biolux. With three coats (including indicator coat), I can go two years between haulouts. Just a month or two ago, I dove to see how the year and a half old paint was doing, and to scrape any hard growth. Other than a very few small barnacles near the waterline and at scrapes in the paint, there was only a very thin smooth layer of slime, and no indicator color showing. I didn't even bother to finish wiping the bottom, it was so clean.

A lot depends on the water in your marina.
There are marinas in my area with very little water flow.
And with the fuel dock's (illegal) spills, the marine life stays away.
So bottoms stay clean in those places.
If I could afford to keep my boat there I would because it is a nice marina. (Harbor Town in Hilton Head is one such.)
And the marina I CAN afford is on a fast moving creek with very clean water. (salt water marshes all around)
I thought at first the flow would keep the slime off (like sailing).
But actually the current just force-feeds the organisms that like to grown on my bottom (and the bottoms of boats around me).
Healthy salt marshes and currents of nutrient-rich water make for fuzzy bottoms.
I used Trinidad SR.
If you're not averse to swimming with mask and fins, get used to diving with a scraper and brush.

Thanks. I think I'll go with Interlux Micron Extra.
