The high-performance hard anti-fouling matrix with a smooth finish reduces friction between the hull and the water, while also helping to increase speed. It is free of copper, making it suitable for boats made of aluminum. Advanced superior 2-season hull protection against algae, dirt, and other microorganisms. It can also be applied to speedboats made of GRP, wood, and steel that travel at speeds over 30 knots. An ideal choice for propellers.
