Why Ultrasonics for Hull
Biofouling?
• Regulatory compliance
• Hull paint biocides negatively impact the environment
• Completely pollutant free
• Significant reduction in total ownership costs
• Bottom paint life extended as much as ten years!

When And Where Does
Biofouling Occur?
WHEN A BOAT IS AT ANCHOR OR DOCKSIDE
• Adherence to the bottom of a boat around 6 knots or less
• Temperature, salinity, and productivity of the organic matter vary
• Boats spend 75% of their time at anchor or dockside!

Ultrasonic Antifouling Systems
TWO BASIC TYPES
• Less than 150 ft – Non-intrusive installation
• Greater than 150 ft – Thru-hull installation

Testimonials and Results
Greenline 33 Hybrid (10m) – Adriatic Sea
“Using one layer of antifouling paint in the spring and the boat
comes out of the water clean in the fall. Neither staff of the
builder nor of the dealer could believe it!”

Testimonials and Results
Ferretti 830 (26m) – Cyprus, Mediterranean
“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 as you can see, there was not much work
left for the diver, so we just went straight ahead this year.”

Testimonials and Results
Redbay - Stormforce 9.5m Rib – English Channel
“Over all we are very impressed. We have kept out fuel costs down, speed up
and greatly reduced the man hours needed to keep the gel coat in shape (it’s
more like man minutes now). And of course we don’t need to have a change of
anti-foul every year or so which saves more money.”

Testimonials and Results
Jeanneau NC9 (9.5m) – English Channel / Bay of Biscay
“I tell you that the Ultra 10 system is successful on my Jeanneau NC9, except
on the top of the flaps and top of the z-drive where they have some little algae.
It remained in the water 10 months and no shells, the result is very
satisfactory.”
