Norwegian coating manufacturer Jotun has unveiled new analysis showing that its Imperial Fouling Protection System “can deliver a carbon footprint that is approximately 50 per cent lower over a 30-year service life compared with a conventional antifouling coating system”, reinforcing the importance of effective hull protection in the superyacht sector.
Hull fouling remains one of the most significant yet overlooked factors affecting vessel efficiency. As marine organisms accumulate on the underwater hull surface, drag increases, leading to higher fuel consumption, greater emissions and increased operating costs. In some cases, a fouled hull can add more than 50 per cent to a yacht’s annual fuel bill.
Designed specifically for the unique operating profiles of superyachts, Imperial uses advanced silyl acrylate self-polishing technology to help maintain a cleaner hull over extended periods, even when vessels spend significant time at anchor or operating at low speeds. This tailored approach enables coating specifications to be matched to a vessel’s sailing pattern, voyage factor and operating environment.
According to the company, the reduced carbon footprint is achieved through fewer maintenance cycles, lower paint consumption and reduced waste generation over the life of the vessel. “Compared with a business-as-usual coating specification developed in collaboration with leading paint manufacturers and the Water Revolution Foundation, Imperial uses approximately half the volume of paint whilst maintaining long-term performance”, the company stated.
