(54) Title: DUAL CAVITY AIR LUBRICATION SYSTEM Fig. 3C 120 102 110 (57) : The invention relates to a dual cavity air lubrication system comprising an air flow splitter with an air inlet pipe branching into a first branch pipe and a second branch pipe, wherein a first passive valve is arranged in the first branch pipe and a second passive valve is arranged in the second branch pipe, wherein said branch pipes are in fluid communication with each other upstream from their respective valves, and wherein said valves are adapted for regulating the flow of air to respective air cavities to compensate for difference in air pressure in said cavities caused by a relative change in level of the cavities due to roll or heel of the vessel.
