Ultrasonic Anitfouling?

Has anyone seen or had experience with this yet?

Welcome to Ultrasonic Antifouling

The premise behind it seems plausible and the cost would be about the same as for a haul out and bottom job for my boat.

Mike—

I'm guessing that you'll be a guinea pig if you get that system. Let us know how it works. Me, I'm sticking with my copper-based antifouling.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

24 amps a day

Never painting again sounds great. As I'm on a mooring, my first question is, "what will this cost me in power?"

From their brochure:

"Technical Specifications
Mains unit - Voltage 220 - 240v
Power consumption 20 - 40 watts depending on model
DC 12v - Power consumption 0.9 - 1.1 amps
DC 24v - Power consumption 0.8 - 0.9 amps
Weight - 1-1.5 kg approx depending on model"

Looks legit. I would go for it. I would look into the warranty, to see if you can get your money back if it is a hoax.

I can understand wanting to keep cockroaches off, but alcoholics....why would I want to keep all my friends away? Oh yeah, we are drunks, not alcoholics...we don't go to meetings.

SD,
I may just have to play Guinea Pig. I am hoping some of our European brethren may have first or secondhand knowledge. Seems to have been in limited use across the pond for a few years now. I've got one more season on my current bottom paint planned, then I might try it next fall. I'll keep everyone posted.

P=VI
Current already has a time factor in it, as it measures the movement of charge past a point relative to time.

So I think you meant 288 watt-hours per day.
Or 24 amp-hours per day (on a 12v system).

Amps per day is a nonsense unit.

You are correct, tager. Nonsense indeed. I should have titled that thread, "24ah per day."

Electricity can be confusing enough, no need to obfuscate readers anymore than necessary!

Talking Massage the little critters to death? No way!

I'm skeptical. What's it do...shake the little buggers off the hull. It appears to operate on a vibration principle similar to one of those fancy massage chairs you see in Sharper Image. When I get in one of those chairs, you can't get me out.
