During the last 8 months, Sonihull system has outperformed my best expectations, on weekly inspections we have seen no sign of growth nor have we had to clean the strainers only for light debris. We have inspected the manifold and coolers with an endoscope and again no sign of growth, which in turn has benefited all auxiliary seawater systems thereafter.

The Sonihull system was very easy to install in SV Delos. Scraping barnacles is now a thing of the past and we’re experiencing much less growth. Just a quick wipe down every few weeks is all that’s required to keep her clean and fast!

The extreme warm waters in this region normally create a very high rate of sea growth on the hull. Upon return to duty, the boat was hauled & found to be in great condition with no adverse growth whatsoever on the hull. We found no need for pressure washing or cleaning thereby eliminating any by-product or toxins going back into the local waters making this an environment-friendly product that really works. We were very pleased with the results from our Sonihull Duo.

I am delighted to see how effective NRG Marine’s “Sonihull” product has performed during our trials. Previously, when we removed the strainers before having Sonihull I found up to 40 mm of growth per week. Now we find that we have very little around 5mm, and is mainly sand and silt. The sea strainers are cleaned on a fortnightly basis now and the system has had a great impact on the growth and minimised the time taken to clean.

We took the boat out today for a scrub after 15 months in the water. The results were remarkable. I have a few photos I would like to share with you, both before and after a quick jet wash, just a thin layer of slime on the hull, nothing more.

The system has been installed for well over 2 years now with excellent results. So much so that the speed log paddle wheel has not needed cleaning since the Sonihull system was installed!

We are very impressed with Sonihull and glad we had it fitted to prospero our Hardy 36 Sedan. Prospero only required a low power wash and no scrubbing!

I have now used Sonihull on two southerly yachts I have owned and I have to admit I am delighted.

I am keen to point out, that although the savings in fuel cost was nice, he was more impressed by the potential savings on wear and tear of his engines not having to work so hard.

Just a quick note to let you know how well your Sonihull system has worked on my 37 ft. Beneteau. The only growth is on the underwater lights with the flexible sealant siloflex which has obviously isolated the ultrasonic from getting through! impressive!

Previously the Yacht had been in the water for two years and showing badly fouled. After I fitted the Sonihull System and when it was lifted out last weekend with very little fouling except for the propeller and drive shaft. Quite impressive.
