Good News for the Barnacles Out West - Copper Paint Going Away

BoatUS Magazine: Is Copper Bottom Paint Sinking?

And good news for the east coast as that is unlikely to happen.

And good news for the western boaters, expensive alternatives will be available. Bottom paint will cost around perhaps $5000 for non copper specialty paints. And the manufacturers say you can get a few years out of the job.
Although, it seems, the specialty boutique paints you wont be able to put on yourself.

Wow, here's a zinc omadine paint for $65 a gallon. Not quite $5000. Obviously not as good an option as copper-yet. Maybe something better will come along soon, till then let's not get all hysterical, there are other options that are affordable.

Nothing to worry about. The Washington State law will get overturned before it goes into effect.

And what is really fair is that it only applies to "small" boats.
Does not apply to the "big" cats......err boats. Only the little guy....err boat.

Exactly why the law will be overturned

I sure hope so.

Unless I sell my boat soon.

Then I won't care...HAHAHAHAHAHAHAHAHAHA Enter white coats and straight jacket.

I'm so happy barnacles will not be going extinct now.

A stuck barnacle is a happy barnacle.

But not with the BoatUS article and data.

A pretty useless bit of "data". Notice the prices on the table for copper paint are for the paint only, and the prices for the other options are for stripping as well as painting. Hardly fair. The fact is that zinc omadine paints are MUCH cheaper than copper, because they don't have all that expensive copper in it. At the price of copper these days it's like gold plating your bottom. No new data worth mentioning here.

Only thing I found interesting in that article was "Hempasil", which despite the name is not a bottom paint made with hemp, LOL. Seems like an interesting approach-

Early fouling release coatings incorporated polytetrafluoroethylene (PTFE) and other fluorocarbon resins. The idea of using Teflon®-coated surfaces – familiar from cookware – seemed ideal because these are both "non-stick" and hard.

However, a non-stick Teflon® surface must be heated to temperatures higher than 300 °C (=572 °F) and despite having low surface energy, Teflon® is actually porous and thus still allowed fouling organisms to establish a mechanical interlock.

Silicone-based elastomeric coatings are an important new way of achieving this "non-stick" effect, exploiting all the advantages of the latest research. Their effect is due to a balanced combination of smoothness and flexibility, along with water-repellent properties related to reduced surface tension.

When such surfaces are stationary, fouling organisms may settle on them. However, the flexibility and low surface tension of a silicone-based topcoat means these organisms get scoured away simply by forceful water movement or the scrubbing effect caused by a vessel's motion. This also means that if there is sufficiently forceful water movement around a vessel's hull, there is normally a natural self-cleaning effect.

As a result of these properties, hulls treated with a silicone-based fouling release system, but which sail less frequently or encounter less forceful water movement, only need cleaning at longer than normal intervals. This is because fouling organisms have difficulty adhering to the surface – which also makes cleaning relatively easy.

They claim it's good for ten years. Sure would be nice. See what some regulation gets us? New products in no time.

And there was a recent thread about a new design of solar panels which would supposedly replace flat panels.


Made by Solyndra.

I'll believe this new miracle paint when I see it actually work in the real world.
