This has worked extremely well
The Ultrasonic antifouling system has worked extremely well for us. We fitted transducers on each of the sea chests and without exaggerating, we had zero growth since the install in February, intervals between cleaning heat exchangers has been significantly extended.

Unbelievable
The Ultra 20 Dual systems have definitely been worth their weight on board the yacht ‘Nilaya’ over the last two years and the difference it makes to the growth on the bottom of the boat has been unbelievable.

Very Impressed
We have just recently lifted “Cypriana” and I am very impressed with the result compared to what I had on my previous yachts in previous years. In previous years we have had to send a diver down to scrub the surface before our 120 mile travel to the lifting dock, since speed would have been cut down by 4 mph, and we would get vibrations due to the growth on the shaft. We had no reduction in speed and there was not much work left for the diver, so we just went straight ahead this year.

A clean hull
I fitted an Ultra10 system to my Nelson 29 motor boat about 2 months after launching. The boat is kept in a marina berth in Poole harbour. At the time the unit was fitted growth had already begun to form on the waterline. After the unit had been in place for about 3 months I slipped the boat prior to a cruise. I was very pleased to find that the only growth was a fine slime, which was presumably that which was there before fitting. The trim tabs had algae on the top but not the underside and there was some around the stern but only at the waterline. It was quite apparent that the unit was having a very beneficial effect and had prevented further growth from forming. I am confident that the unit will keep algae at bay now that the hull has been power-washed and the unit is in operation on a clean hull.

Effective
A boat moored next to “Why Knot” from 25th June until 10th July developed growth of shell animals and algae but the hull of “Why Knot” remains totally clear. Even the paddle wheel of the speedometer no longer needs clearing when, previously this was required regularly. The situation remained the same right through to September clearly showing the effectiveness of the Ultrasonic antifouling system.

Proved effective
Ultra system has considerably reduced the infestation of barnacles and that the performance of the boat did not deteriorate significantly during the season. The system has proved to be effective in discouraging barnacles and other animal marine fouling.

Efficiency is at its highest.
In the Channel Islands we suffer from heavy fouling of the hull and have to lift the boat up to 3 times a year for power washing and re-coating the conventional anti-foul paint. With this system we have found that it still requires anti-fouling but just once a year and has eliminated the need to lift the boat out during the season saving valuable time and money. The system is easy to install even for the average person and with less growth the performance is not decreased and fuel efficiency is at its highest.

Cariad 2 , business , .
Could not believe our eyes
We could not believe our eyes as Cariad 2 was lifted clear of the muddy River Exe water. Not a trace of shell or weed fouling and only a slight slime just below the waterline which was easily removed by our domestic Karcher water jet. Thanks to your product we have saved at least a morning’s hard work and a lot of back ache.

No evidence of excessive weed
I had a diver down in late December two months after fitting the system. There was no evidence of excessive weed only one barnacle on the prop 40 minutes and the hull was clear. Very satisfactory. The boat had been antifouled aprox 18 months prior by the previous owner and cleaned and washed twelve months prior when the boat had been slipped for survey . There is an audible noise at night as out of necessity the system is fitted beneath my bunk however it is not loud enough to cause either my wife or I to need to switch it off at night.

Great
I have a Bertram 35 and we fitted the device in August. The boat was previously antifouled in Sept 2007. At the time of fitting the unit we had weed on the waterline and other boat owner’s near us had divers cleaning their hulls.After a month we took the boat out and when we came back all the weed was gone. Subsequently we slipped the boat in Sept and the hull was clean. The shafts and trim tabs had molluscs on but they were already attached from last year.
