A boat hull having elongated concave tunnels is described. The elongated concave tunnels reduce the amount of drag and water friction with the boat hull in contact with water. A faster plane mode, better speed, stability, and fuel efficiency are achieved. Air is forced through the elongated concave tunnels during planing, thus producing lift and results in the boat achieving the plane mode faster. At cruising speeds and high speeds, more lift is generated by faster air passing through the elongated concave tunnels thus giving generous lift to the boat hull and hence producing minimal friction and drag in contact between the boat hull and the water surface.
