Knot Me... maybe

A not Anti-fouling anti fouling?

Recommended Posts

I lost that piece of string.

One thing I do know is nature ability colonize is most tenacious.

Would we want it any other way?

 

Further Update on diy copper epoxy with west.

Dove the hull yesterday @Boulder bay

Blue half a tank just to do one side.

Hull was pretty good for most species...except oysters. Epic fail.

That said, today was first clean of year.

Had a cwt of oysters in a band around hull. Complements of the

westpark incubator. Shredded a few body parts "relocating" them.

Sharp suckers.

 

Queer, actually how they seem to prefer a certain depth.

They seem to love coppercoat or my configeration anyhow.

Strange how it worked great for first year.

Now I definitely have to come out

Deja vu....like a recurring nightmare.

What bugs me with the slippery stuff is recoatability.

Whats the point if you have to grind/scrape it all off and start again when its lost its effacacy.

And, its seem most of them are softish which means scraping is like shooting your foot..

 

Think I might leave the 100% solid Cu coat but put a band of water based coppercoat with an approved biocide in the oyster zone.

 

Anybody tried Hempel silic one?

Seems Hempel is trying the exact opposite as well.

Hydrophilia...attracting water to the release surface.

 

Theory being is the colonizers don't identify it as a hard surface suitable for colonization.

So they don't attach.

So you are actually dragging along a thicker boundary layer?

Sounds like marketing to me....+ a heavier boat.
