PROVISIONAL APPLICATION FOR PATENT
INVENTION TITLE
Twin Axial Fan with inverted ruddervator steering for an air boat
BACKGROUND OF THE INVENTION
Problem Solved: This system solves the inherent problems of conventional air boats. First of all they are extremely susceptible to taking on water, sinking or tipping over. Second they are extremely noisy. Third they are very tall and do not go under bridges well.
A conventional Air Boat has a high profile that prevents clearance under many bridges and will tilt in a slow turn to the point of taking on water, sinking or tipping over!
The propellers are very loud.

My design brings all the equipment down into the boat for a low center of gravity and thrust. The "Twin Axial Fan" system puts the thrust on the port and starboard side of the transom instead of in the middle of the transom like the conventional system does. The inverted ruddervators tilt the boats hull in the proper direction for the turn so as not to take on water, sink or tip the boat over.
My design has fans instead of a propeller that are subsonic and produce much less noise, about the same as a lawnmower.
The overall height is much less so my boat can fit under bridges that the conventional airboat will not.
This airboat would be best suited for shallow water operations where noise is not much of a factor. Unlike conventional airboats this boat is completely maneuverable in fast and slow speed turns left or right. It is also completely maneuverable in accelerating and decelerating turns left or right. My prototype handled perfectly in all these cases and can be seen doing so in the first sea trial test (video was taken, click on link below). Also note that this boat is air cooled so salt water is not used inside the engine which causes mechanical failures on water cooled boats. There is no propeller in the water to destroy marine environments, plants and animals. This boat is also much lower and can go under bridges that other airboats cannot. The efficiency of axial fans allows for a much smaller engine to be used so as to increase fuel efficiency. Conventional Airboats burn 5 to 15 or even 20 gallon per hour of fuel. My prototype with a 13 HP motor ran for about an hour for less than 1 gallon of regular gas!!

Financial information

I have an open mind on this Patent. I would love to join an existing Company to see this invention thru to production. A licence with royalties or an outright sale will also be considered.

I have been searching for several years for something like this and as usual just gave up and built my own. I know of nothing like this on the market now.

My opinion is that Air Boats are not so popular now because they are mostly home made and clumsy. If there was an alternative, say an off the production line model at a fair price! The interest would be greater than now. Considering the environmental impact of conventional boat drive methods vs an Air Boat! This boat could be produced for much less than a comperable boat with an outboard motor. Being a shallow water boat it would be much better for so many reasons like, not breaking the prop on obstructions, not so prone to run aground, not harming people or marine life in the water, not using salt water for engine cooling which causes so many problems with engines not to mention the extra maintenance involved! There can be a model with a smaller engine for economy or it can be built up for speed. The list goes on.

I do have several Ideas that would compliment this design. That is why I feel I should be involved with its production. However if the price is right I may consider handing over all future design aspects with the sale!

Included in the sale is the US Provisional Patent, the working prototype, professional drawings, video, photo and notes of testing and results.
Foreign filing licence granted 6-7-2013 US 61/829,093 (app # same).
