A system for reducing drag on a marine vessel (2) comprising a plurality of outlets (4) provided in the hull of the vessel (2) for delivering a layer of air bubbles between at least a portion of the hull and the water: at least one venturi tube (6) adapted to supply air and water to one or more of said plurality of air outlets (4): at least one seawater inlet (8) located in the bow region of the vessel (2) adapted to supply seawater to the at least one venturi tube (6) as the vessel (2) moves through the water: at least one seawater pump (10) adapted to supply seawater to the at least one venturi tube (6): at least one ambient air inlet port (16) adapted to supply ambient air to the at least one venturi tube (6) such that ambient air is entrained into sea water flowing through the at least one venturi tube (6): a compressor (18) supplying compressed air to the at least one venturi tube (6): a controller adapted to regulate the flow rate of sea water supplied from the at least one seawater pump and to regulate the supply of compressed air from the compressor to optimise the delivery of air bubbles through the plurality of outlets in the hull and thereby optimise drag reduction of the vessel.
