- 1. Field of the Invention
- The present invention relates to a pontoon boat provided with a jet propulsion unit located within each pontoon and the jet propulsion units powered by an engine either located within the interior of the pontoon or on the deck of the pontoon boat above the pontoon where the jet propulsion unit is located. In a pontoon boat with two pontoons, there is an engine and jet propulsion unit configured with each pontoon.
- 2. Description of the Related Art
- Various types of watercraft have been developed for different types of boating activities, for example hydroplane type hulls for racing, monhulls for load carrying capacity and catamarans for speed and stability. The pontoon boat is unique in design and is constructed from separate components for the pontoons and the deck and generally offers a relaxed ride for a number of passengers, is usually equipped with an outboard motor and typically operates at slower speeds. Seating areas, lounging areas, storage compartments and chairs and tables are usually arranged on the deck of the pontoon boat for cruising and for accommodating a variety of recreational activities. The layout of the deck on pontoon boats usually permits passengers to stand and move easily throughout the passenger area. Pontoon boats are usually equipped with an outboard motor but these motors are not suitable for use in shallow waters, rapids, weed infested waters, or areas with submerged rocks or other objects that can damage the projecting propeller shaft of the outboard motor.
- It is an object of the present invention to provide a pontoon boat with a jet propulsion unit mounted within the pontoon. The boat is propelled by sucking water from the pontoon bottom through the inlet of the jet propulsion unit which is powered by a separate engine.
- The water is discharged rearwardly or aft through a steering nozzle propelling the boat forward.
- A further object of the present invention is to provide a watercraft which combines the attributes of a pontoon boat but with the advantage of being capable of operating in very shallow water and is also capable of additional maneuverability than a pontoon boat equipped with an outboard motor.
- A further object of the present invention is to provide a jet propulsion source located in the pontoon sufficient to move the pontoon boat at varying speeds through the water.
- A further object of the present invention is to provide a pontoon boat with a jet propulsion drive including a deck that can be configured in a manner consistent with a number of seating, lounging and storage layouts. The passenger areas on the deck can be configured to a variety of layouts to provide the amenities of an extremely comfortable watercraft capable of seating multiple passengers while providing sufficient storage space for all necessary items for a commercial or recreational watercraft.
- A further object of the present invention is to provide access hatches or ports through the deck and the pontoon that can be configured in a manner consistent with marine engineering to be water tight to allow access to service the engines and the jet propulsion units.
- Another object of the present invention is to provide a jet propulsion pontoon boat with a larger useable deck area than a pontoon boat with an outboard motor. Pontoon boats usually have a shortened rear deck to accommodate an outboard motor.
- Still another object of the present invention is to provide a jet propulsion pontoon boat with a removable motor compartment cover on the deck that forms a storage area, or a seat bottom and seat back, or a lounging surface area
- The jet-propelled boat of the present invention may be furnished with an engine, a multiple cylinder engine provided with a plurality of cylinders, or other engine types sufficient to power the jet propulsion unit. Other methods known in the art for powering the jet propulsion unit may be used. Transfer of power from the engine to the jet propulsion unit may be through a belt drive, direct drive shaft, a drive shaft connected through one or more gear boxes, or power transfer units, or transmissions, or other methods known in the art for power transfer in a straight line or at various angles of alignments between the jet propulsion unit and the engine.
- Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
