I used Pettit SR40, great results, better than Interlux CRC

The reason the Pettit SR40 probably works better than the Interlux Micron CRC is the Micron requires a fairly high speed to start ablating at... and isn't as useful on sailboats as slow as yours.

Seriously, the Pettit ablatives start to ablate at speeds as low as 4 knots or so, while the Interlux ablatives tend to start up around 7+ knots or so.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

We switched to the Pettit SR40 last season as well and are very pleased with the results, especially in the slime reduction department. Much better than the Micron.

I believe I've read somewhere that the West Marine CCP is the Pettit without the Dual Biocides....

I'm just doing a touch up this year using the last of the Pettit Hydrocoat I have on hand, but after talking it over with the Pettit rep at the boat show, I may use SR40 next time around.

I've been really pleased with the Hydrocoat, both for price and ease of application/clean up, but we do get a bit of slime. I asked, but apparently you can't add the anti-slime agent to the water based Hydrocoat. If you could, I'd say it would be the perfect product for the Chesapeake.

Last spring I applied WM PCA Gold which is the WM version of the Petit with Irgarol. Late summer/early fall there was significant sliming, at least around the water line (but that happened to a lot of boats in my marina, regardless of paint used). The boat's been in the water all winter and it appears most of the slime near the water line has abladed away simply from movement of water around the boat in the slip. The water's clear enough now that I can see a barnacle or two have grown on the bottom. Some small splotches of the paint have also come off (I put blue over black so it's easy to see), especially near the bow. I don't know whether the blue simply abladed away that quickly or I had an adhesion problem. I plan to haul the boat and touch up the PCA Gold in the spring and reassess next year.

OK I am going to go your route Shaun. I have had good results with the micron extra and have gotten 2 seasons from it, but the slogh off of the ablative at lower speeds makes sense to me.

Old Bay has a really great deal for hauling, powerwashing and painting. Gonna use the Petit SR40 for the next two year stint.
