Interesting Update on Bottom Paint Study

From today's 'Lectronic Latitude, comes word of some interesting results that turned up in a bottom paint study:

"Bottom Paint Study Update

"May 21, 2008 – Richmond

The bottom of our boat looked like a patchwork quilt - grassy green, spotless black and slimy brown. The brownish area at the trailing edge of the keel was leftover herring roe from this spring's run.

"We have to admit that, when we agreed to participate in a 'green' bottom paint study last year, we were a little skeptical that the more environmentally friendly paints would work as well as the tried and true, if terribly toxic, copper paint. Our boat was hauled at KKMI in Richmond last November, where three different paints were applied to its bottom in six sections: a control of non-ablative paint with 67% copper content, and two experimental copper-free paints from different paint companies, both with 3-6% Econea, the biodegradable and significantly less toxic compound being tested in this study."

Interesting stuff!

Can't wait to hear about it when they pull it out again.

I need something for my aluminum hull and the bottom paint that is available now is near worthless. I hope this stuff really does work.

I think all of us with alluminium hulls are awaiting the next generation of antifouls to equal or even better the now banned TBT based ones. Apparently the NZ and Aussie Navies are still using the TBT ones. Maybe the US navy is too?

From yesterday's 'Lectronic Latitude, comes word that another 2 1/2 years of the study have been analyzed, with some surprising results. If the water-based paint is ever identified and can be subjected to conditions more varied than those in San Francisco Bay, it may prove to be "the answer," (for some, in certain conditions.)

Bottom Paint Study Update

"Since the fall of '07, this writer and her husband's boat has been part of a bottom paint study to test the efficacy of the biocide Econea, an eco-friendly product produced by Janssen Pharmaceutica and sold to different paint companies. Three paints were applied to the bottom of our Crealock 37 — one control paint containing 67% copper, one solvent-based test paint and one water-based test paint. After a year, the water-based paint, in our opinion as boat owners, was not only the best among the three, but the best paint we'd ever used. There was zero hard growth on all three — which made them equally 'successful' in the eye of study coordinator Jack Hickey, as that is the study's primary focus — but the water-based paint had very little slime or grass. The other two were mini-ecosystems unto their own."
