A frictionally reduced hull is provided for a marine vessel, the hull having a water line, a bow end and an aft end. The hull has a first opening below the water line and a second opening below the water line. The first opening is closer than the second opening to the bow end. A first conduit extends from the first opening to the second opening, whereby water flows into the conduit through the first opening and passes through the conduit from the first opening towards the second opening, exiting at the second opening. A second conduit extends into the first conduit between the first opening and the second opening, fluid being drawn into the first conduit via the second conduit and exiting at the second opening.
