Benefits of technology

[0004]This invention addresses the status of maintaining any arc of travel of a sail boat with acqualerons (fins), the design of said fins and gear systems are completely balanced requiring little pressure to operate. If the vessel is traveling north and the wind is from the east, lowering the right side fin downward and raising the left said fin results in controlled travel. Due to equal pressure on both sides of the keel, by said fins, the established arc will remain constant, the said fins work exactly like the aileron on a plane. During racing, said fins will control arc of travel producing greater speed, when said fins are not required, said fins are retracted eliminating any drag. When conditions are proper said fin can be used as a hydrofoil thereby increasing speed of vessel. Said fins used for

Embodiment Construction

[0014]The primary embodiments of this invention is the gears in FIG. 1 with a round tapered gear 1 between two round tapered gears 2 and 2a on either side of gear 1. When gear 1 is turned, gear 2 moves in the opposite direction of gear 2a turning shafts 3 and 3a which are attached to said fins 4a and 4b. When Gear 1 turns clockwise both said fins 4a and 4b turn in opposite arcs creating a downward pressure on said fin 4b and upward pressure on fin 4a, boat is traveling north and wind is from east creating a controlled arc of travel. A cross section of said fin shows top 4a and bottom 4b with shaft 3. 5 shows piston which retracts said fin when said fins are not in use. When gear 1 is disengaged gear 1a is engaged on gear 2 and 2a turning said fins 4a and 4b in the same degree of elevation resulting in a hydrofoil raising vessel upward reducing amount of vessel in the water thereby increasing its speed. FIG. 2 is a cross section of keel with said fins 4a and 4b on both sides of the k...

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.

Description

BACKGROUND OF THE INVENTION[0001]This invention is similar to the ailerons of an airplane which maintain a horizontal state. The fins (the aqualerons) are controlled by a set of gears which are in opposite planes on each side of the keel. Said fins create a downward pressure on one side and an upward pressure on the other side keeping vessel in any position from the horizon. Prior art does not address a simple and effective method to control any angular arc of travel. Cohen rotates a portion of the keel to maintain arc of travel. When the fin is applied, it creates a drag plus arcing the vessel in the direction of the applied fin requiring the rotor to compensate for the arc resulting in a greater drag. Serfess also has a section of the keel which rotates. Regnolds keel also has a section which arcs off the keel. Prior art addresses the problem from the rudder and keel, this invention addresses the problem on either side of the keel controlling the arc of travel. When conditions are...
