I had no idea you were going under the knife. I hope all is well. Or at least, I hope all will be well very, very soon. I can't speak for your Dutch, but I think the morphine has improved your English. (LOL, Just kidding brother. I have tremendous respect for your multi-linguistic skills. Unlike yourself, this ignorant American can only speak one language
). God speed for a quick recovery, brother. I'll be thinking of you.
I've never seen a dvice like that before, but I like the logic bhind it. It would seem that you would need to take the hull down to fiberglass (or barrier coat if one was applied), then a hard anti-fouling would need to be used instead of an ablative paint. Since we all have planing hulls, I would think that 99% of us are using ablative paint which is designed to 'self-clean' by wearing growth and paint away through hull friction at planing speeds. This would be counter-productive to the sonic solution. I would think a hard pain like what is used on displacement vessels (sailboats and trwalers) instead.
