Abstract

An air dimple system (200) for a hull (102) of a vessel (100) is disclosed herein. In a first embodiment, the air dimple system (200) comprises an array of discrete air dimples (202) to be arranged at the hull's bottom (108) with the discrete air dimples (202) to be arranged between respective longitudinal structural members (116) of the hull (102). The air dimple system (200) further includes an air injection device for supplying pressurized air to the array of discrete air dimples (202) for creating corresponding air cushions at the respective air dimples (202).
