ANTI-FOULING PORN: Preliminary Ultrasonic Results

Ultrasonic Antifouling test results

Only a boatowner could view an image like this as being orgasmic. You'll recall I'm testing some gear sent over from Ultrasonic Antifouling Ltd. in the UK--in-hull transducers that go clickety-click 24-7 and supposedly prevent nasty critters from growing on Lunacy's hull.

Well… Lunacy got hauled a couple of weeks ago after two months in the water with her two new transducers clicking away, and the results seem pretty damn impressive to me. I can't really say anything definitive yet. Two months ain't that long, and Lunacy does have a new suit of anti-fouling paint on… BUT the harbor in Portland, Maine, where she lays, is normally a high-growth area, and the boat has been mostly idle, and I have no reason to believe that Lunacy's new zinc-based ablative bottom paint is any more effective anti-fouling-wise than her old zinc-based ablative bottom paint (which wasn't really that effective)...

SO I am tentatively, provisionally, and marginally ecstatically encouraged by these photographs.

I couldn't attend the haul-out, so I asked Jeff Stack, the service manager at Maine Yacht Center, to be sure to take pix when the old girl was plucked from the briny. He admonished the crew NOT to pressure-wash the hull until he could deploy his camera. And as soon as he saw her, he was sure they had disobeyed orders.

But they hadn't. Here's some more pornography on which to feast your eyes:

The other relevant test result concerns power consumption. The Ultra 20 system I installed was advertised as consuming 24 amps a day. I can't say exactly what the actual consumption on Lunacy was, but I can say that her onboard power-generating systems (a 150-watt solar array and an Air-X wind turbine) had no trouble meeting the demand. Every time I visited and/or used the boat, the batts were all topped up. Of the 60 or so days between the Ultrasonic installation and the haul-out, the boat was actively used for about 10 days, during which time the Ultrasonic system was turned off.

I'll have more comprehensive results after we get thru next season. So far, however, the trend is distinctly POSITIVE.
