We have a similar coating called Ecospeed. The trouble is that anti-fouling paints are fast being driven out of existance by legislation so new ideas are needed. Unfortuately the latest paints are basically a resin coating, which although does all the fantastic things they claim, it only does it whilke it remains clean. We used to clean the hull every six months with anti-fouling paint but now we have to clean it every six weeks!! If we don't we can see the fuel consumption slowly rise.
The claims are true but not for very long!!
