A watercraft incorporates a vertically elongated displacement hull section to elevate the riders of the watercraft well above the water level when the watercraft is up on plane. During normal low-speed displacement hull-type operation, the elongated displacement hull section remains submerged, and does not appreciably affect the stability of the watercraft. When the watercraft is accelerated to planing speed, however, the elongated displacement hull section rises out of the water, and the watercraft planes on the planing surface disposed at the bottom of the elongated displacement hull section. In this manner, the operator/riders are lifted a significant distance above the surface of the water. The watercraft further incorporates an elongated displacement hull section having a bulged section which is sized to accommodate the watercraft engine within the elongated displacement hull section. This bulged section allows the assembled engine to be installed and/or removed from the watercraft, yet minimizes the overall volume of the elongated displacement hull section, thereby reducing the buoyant forces induced on the watercraft hull by the elongated displacement hull section. The lower position of the engine within the hull also lowers the center of gravity of the watercraft, thereby improving the watercraft's stability and handling characteristics. |
