Algae causes fouling on the hull, the UltraSystem destroys algae and removes the cause. Scientifically proven and designed engineered, UltraSystem Series II prevents weed and barnacle growth which reduces drag, maintains hull performance and saves fuel – a significant factor for motorboats! A clear hull reduces the need for lift outs and scrubbing and changes the way boat owners use the various paint products and the frequency when those products are applied. It’s environmentally friendly and easy to install with the boat in or out of the water. Developed by the world’s leading and original manufacturer since 2007, UltraSystem Series II is the most advanced system on the market today.
