Come to Mallorca in March when my boat is out of the water and you will see several layers of barnacles on the props and rudders.
Huge problem in the Med.

Just read that Maclaren is "developing a system which can repel material from a windshield via high-frequency sound waves."
Sounds like we can use that as the base for a good Ultrasonic antifoul

Hmm, read magazine article, still not impressed. I kept a boat in Kip marina for @ 9 months. That boat had had two coats of Internationals intraspeed ultra two years previously. Nothing on props and shafts.
After 9 months in Kip I sold the boat and it was lifted for survey etc. How much fouling was on the bottom and props????
none.
Discovered recently that my current boat has had ultrasonic antifouling system fitted (can't recall which one) - guess what - its been removed by previous owner

Photo as requested
I attach a photo of Serendipity after she hauled out and was washed down in Grenada on completion of our circumnavigation in April 2014. She had last been hauled out in Auckland in December 2012. In the intervening 16 months she had sailed the Indian and South Atlantic oceans. There were a few barnacles in the bowthruster tunnel and between the skeg and the rudder but otherwise she was clean.
A green algae slime accumulates over time but this wipes of with a cloth. I have dived and cleaned that off before each long passage but otherwise th bottom has needed no maintenance in circa 18,000 miles sailed.
