Best color/colour Antifouling?

[bill good]

I've given up on antifouling!! & have applied a new (to me) product called OceanGard. Used 1/2 the usual quanty to cover the bottom. Black looks good. Now just waiting for the critters to give their reports!! Claim better than 3 yrs & it is a 2 part product.
Any one else tried this product?
Regards Bill

Mark! ya poofdah, you will go to any lengths to have people discuss your bottom.

Any colour, but put lots on, we generally do 8 coats. Only haul every 6 years or so.

Sure about that?

Great advise, not that cheap initially but it does work that way.
Longer periods between haulouts.

Personally I don't paint, I dive and scrape as needed, and sail.
May paint at a later date. Don't really get that much slime and just a few mussel sets.
Works for me now.

From the Wikipedia entry on barnacles. The cyprid stage has an eye, and it can swim :

The cyprid larva is the last larval stage before adulthood. It is not a feeding stage; its role is to find a suitable place to settle, since the adults are sessile.[7] The cyprid stage lasts from days to weeks. It explores potential surfaces with modified antennules; once it has found a potentially suitable spot, it attaches head-first using its antennules, and a secreted glycoproteinous substance. Larvae assess surfaces based upon their surface texture, chemistry, relative wettability, colour, and the presence/absence and composition of a surface biofilm; swarming species are also more likely to attach near other barnacles.[8] As the larva exhausts its finite energy reserves, it becomes less selective in the sites it selects. It cements itself permanently to the substrate with another proteinacous compound, and then undergoes metamorphosis into a juvenile barnacle.[8]

You mentioned color, they didn't specify which? Dang!

Before I painted Red thinking it had more copper... now I alternate between Red and Blue so I can see the spots I missed.

Well, a little research quickly proves me wrong! I looked at one abstract that stated that the photoreception of the cyprid stage allowed them cement themselves in closer proximity to other barnacles and they favored red.

Still, they gain successful attachment primarily due to their great number of offspring and random current flow.
