Motorized watercraft having trim stabilizers

Abstract

There is provided a motorized watercraft having a hull. The hull has an upper portion located substantially above the water line. Thus hull includes a front portion and a rear portion. The upper portion of the hull has a front portion and a rear portion. A drive motor being attached to the rear portion. First and second stabilizers are attached to the front portion of the hull so that the hull may be stabilized during operation by providing a downward force on the front portion of the hull.

1 . A motorized watercraft comprising: 
 a hull; said hull having a rear end, a front end and a central portion; said central portion located substantially halfway between said front end and said rear end; said front end being susceptible to upward movement due to wave action and the relative movement of air when the watercraft is moving forward;    said hull further including a front portion; said front portion including said front end and the portion between said front end and said central portion;    said hull including an upper portion which is located above the water line of said hull;    at least on stabilizer;    said stabilizer extending from said front portion and said upper portion, whereby air moving over said stabilizer produces a downward force, wherein the likelihood of extreme upward movement of said front end is reduced.    
     
     
         2 . A motorized watercraft as set forth in  claim 1 , wherein said at least one stabilizer includes first and second stabilizers; said hull having a right side and a left side; said first stabilizer extending from said right side and said second stabilizer extending from said left side.  
     
     
         3 . A motorized watercraft as set forth in  claim 2 , wherein said stabilizers are rotatable to adjust the amount of downward force on the front portion of said hull.  
     
     
         4 . A motorized watercraft as set forth in  claim 3 , further including a rotatable rod; a pair of holes in said hull adjacent to said stabilizers; said rod having first and second end portions; said rod extending through said hull; said first end portion of said rod connected to said first stabilizer; said second end portion of said rod connected to said second stabilizer; said rod enabling said stabilizers to rotate.  
     
     
         5 . A motorized watercraft as set forth in  claim 4 , wherein said hull includes a cavity; a motor located in said cavity; said motor connected to said rotatable rod for moving said rotatable rod and thus moving said stabilizers to a desired position.  
     
     
         6 . A motorized watercraft as set forth in  claim 5 , further including a connecting rod, said connecting rod connecting said motor to said rotatable rod.  
     
     
         7 . A motorized watercraft as set forth in  claim 6 , further including a radio receiver; said radio receiver responsive to a remote control transmitter; said radio receiver electrically connected to said motor for controlling said motor, whereby the position of said stabilizers may be controlled by said remote transmitter.  
     
     
         8 . A motorized watercraft as set forth in  claim 2 , wherein said stabilizers each have a tip extending upwardly therefrom.  
     
     
         9 . A motorized watercraft as set forth in  claim 8 , wherein said tips are approximately 90° with respect to the major surface of each of said stabilizers.  
     
     
         10 . A motorized watercraft as set forth in  claim 2 , wherein each stabilizer has a leading section and a trailing section; a bend located between said leading section and said trailing section forming an angle, wherein the trailing section extends upwardly from the leading section so that air flow over the stabilizer may be diverted upwardly.  
     
     
         11 . A motorized watercraft comprising: 
 a hull; said hull having an upper portion; said upper portion located substantially above the water line of said hull; said upper portion having a front portion and a rear portion; said rear portion having a drive motor attached thereto;    first and second stabilizer;    said first and second stabilizers attached to said front portion, whereby said watercraft may be stabilized during operation.    
     
     
         12 . A motorized watercraft as set forth in  claim 11 , wherein said stabilizers are adjustable so that the angle of incidence with respect to the wind may be adjusted for varying conditions, thereby adjusting the downward pressure on the front portion of said hull.  
     
     
         13 . A motorized watercraft as set forth in  claim 11 , wherein each stabilizer has a leading section and a trailing section; a bend located between said leading section and said trailing section forming an angle, wherein the trailing section extends upwardly from the leading section so that air flow over the stabilizer may be diverted upwardly.  
     
     
         14 . A motorized watercraft comprising: 
 a hull; said hull having a rear end, a front end and a central portion; said central portion located substantially halfway between said front end and said rear end; said front end being susceptible to upward movement due to wave action and the relative movement of air when the watercraft is moving forward; 
 said hull further including a front portion; said front portion including said front end and the portion between said front end and said central portion;  
 said hull including an upper portion which is located above the water line of said hull;  
   first and second stabilizers; 
 said first and second stabilizers extending from said front portion and said upper portion, whereby air moving over said stabilizer produces a downward force, wherein the likelihood of extreme upward movement of said front end is reduced;  
 said hull having a right side and a left side; said first stabilizer extending from said right side and said second stabilizer extending from said left side;  
 said stabilizers being rotatable to adjust the amount of downward force on the front portion of said hull;  
   a rotatable rod; a pair of holes in said hull adjacent to said stabilizers; said rod having first and second end portions; said rod extending through said hull; said first end portion of said rod connected to said first stabilizer; said second end portion of said rod connected to said second stabilizer; said rod enabling said stabilizers to rotate; 
 said hull includes a cavity; a motor located in said cavity; said motor connected to said rotatable rod for moving said rotatable rod and thus moving said stabilizers to a desired position;  
   a connecting rod; said connecting rod connecting said motor to said rotatable rod;    a radio receiver; said radio receiver responsive to a remote control transmitter; said radio receiver electrically connected to said motor for controlling said motor, whereby the position of said stabilizers may be controlled by said remote transmitter.
