  Anti-fouling purpose  Red area is coated with anti-fouling paint Prevents marine growth (barnacles, algae, mollusks. Reduces drag, fuel consumption, and maintenance Copper-based paint Traditional anti-fouling paints contain copper compounds (cuprous oxide). Copper gives the paint a red / reddish-brown color Copper ions are toxic to marine organisms, preventing growth Reduced fuel consumption Clean hull improves fuel efficiency by up to 10–15% Less fouling = smoother hull = lower water resistance Corrosion protection Acts as a protective barrier Reduces direct contact between steel hull and seawater Slows down corrosion Industry standard (not mandatory) Red color is widely recognized Cost-effective and proven over decades Other colors (blue, black, green) are also used today Easy inspection during dry dock Strong contrast makes it easier to spot: Damage Wear Fouling patterns
