ABSTRACT:
The invention relates to a stabilizing hull for watercraft. The hull comprises a series of sealed, hollow, aluminum tubes. The entire structure is held together with a lightweight aluminum frame. The pontoons are preferably six-inch diameter, aluminum pipes with a circular cross section. However, different materials, different size pipes, or pipes with different cross sections may also be used. The pontoons are arranged in a side by side parallel configuration, with the aluminum frame connected to the top of each pontoon. Each of the pontoons is sealed at both ends and is turned up at one end to form the bow of the hull. The frame supports a planar sheet that acts as the floor of the boat. A load leveler may also be attached to an extension connected to the rear of the frame to improve maneuverability through the water and to increase the load support of the hull. A further embodiment of the hull includes two additional pontoon units on each side of the hull. Each of the pontoon units has a top pontoon and a bottom pontoon. The units are attached to each side of the frame using three metal brackets. The bottom pontoons of each unit are positioned side by side with the pontoons under the frame, and are also turned up in the front, while the top pontoons of each unit extend from the point the bottom pontoon is turned up, to the rear of the bottom pontoon. The number of pontoons, size of the pontoons, and the spacing between the pontoons, can be changed for different weight capacity needs.
