DITHERED MARINE UV REFLECTIVE COATING WITH COLOR

The invention provides a vessel (1) comprising a hull (21) with a coating layer (100), the vessel (1) further comprising an anti-biofouling system (200) comprising an optical medium and a light source configured to provide UV radiation, wherein the optical medium (270) is transmissive for light, wherein the optical medium comprises a radiation escape surface and a second optical medium surface with at least part of the transmissive optical medium material configured between said radiation escape surface and said second optical medium surface, wherein the optical medium is configured adjacent to at least part of the coating layer with the second optical medium surface configured closer to the hull (21) than the radiation escape surface, wherein the anti-biofouling system (200) is configured to provide said UV-radiation downstream from said radiation escape surface in a direction away from said hull (21), and wherein the vessel (1) further comprises a pattern comprising colored segments and UV reflective segments with at least part of the transmissive optical medium material configured between said pattern and said radiation escape surface.
