A serious issue for any water-borne craft is that of marine fouling. Seaweed and sea life are remarkably adept at adhering to boat hulls. This condition causes two problems. Firstly, fouling causes a substantial loss in hull efficiency, increasing power consumption and reducing range. Secondly, it increases the risk of species migration and entry into sensitive environments. Cleaning large boats is costly and time consuming due to the need to dry-dock and manually clear the bio-burden. An ideal solution would avoid the need to dry-dock the boat.
