Fins to control angular travel of sailboats and wake control

Abstract

As Aileron (fin) is to airplanes and aqualeron is to ships, a device with fins position on both sides of the keel in a horizontal position where a set of gears controls the fin on one side in a downward arc and the other side in an upward arc providing a controlled below water force to maintain any arc of travel on a sail boat, or as a hydrofoil. A set of fins positioned on the bottom of a sailboat eliminating the keel. A set of fins positioned at the bow of a motor boat providing a downward force of the bow. A set of fins on either side of the stem of a power boat, when activated, swing out directing water to the rear of the boat filling the cavity created by the boat to eliminate the wake. A set of fins on both sides when opened to a tube allowing a force of water to enter and empty at the rear of the boat filling the cavity with instant water thereby controlling a wake free operation.

1 . Use of fins or aqualerons to stabilize said sail boats in any arc of travel either vertical or any angle from the vertical. Said fins can be used as a hydrofoil. 
   
   
       2 - 10 . (canceled) 
   
   
       11 . When two or more said fins are on a vessel a set of fins may be used to control arc of travel and the remaining set of fins may be used as a hydrofoil. Said fins are retractable. Said fins in  claim 1  shown in  FIG. 4  are located at the bottom of the vessel wherein said fins eliminate the use of a keel. Said fins may also be installed on sides of the vessel out of the water and lowered when in use. Use of tapered gears in  FIG. 1  control said fins for travel in hydrofoil. 
   
   
       12 . Fins in  claim 11  controlled by gears at the bow in  FIG. 5  when arced in a downward arc from the horizon maintains bow of boat in water. Fins at stern operate by pistons to open and close fins which extend beyond stern, when opened divert water to rear of boat, when closed do not create drag at high speed. Said fins also control flow of water from bow or sides of craft through tubes exiting to the stern for wake control.
