Abstract
A device for improving steering in a watercraft. The device has a frame attached to two parallel blades. The device pivotally attaches to an attachment point on a steerable nozzle of a watercraft. Frame of device has two curved mount brackets that are substantially parallel to one another having a first end and second end. A mount bracket connector connects the two mount brackets at the first end. The mount bracket connector includes a down force regulator, that folds back over mount bracket connector. Each mount bracket terminates at its second end with a lift tab. Lift tabs direct water flow in a generally downward and outward direction as watercraft moves through the water. Each mount bracket bolts to a blade, thereby holding the two blades securely parallel to one another.
Claims20
A device for redirecting a jet stream flow created by a watercraft when traveling in a body of water, having a pump assembly, wherein said pump assembly a steerable nozzle, said device comprising:
- a first rudder blade coupled to said steerable nozzle;
- a second rudder blade coupled to said steerable nozzle;
- and
- a frame coupled to said first and second rudder blade, wherein said frame has:
- a first mount bracket having a first and second end,
- a second mount bracket having a first and second end,
- a mount bracket connector connected to said first end of said first mount bracket and to said second end of said second mount bracket,
- a first lift tab attached to said second end of said first mount bracket, and
- a second lift tab attached to said second end of said second mount bracket;
- and
- wherein said frame is coupled to said first rudder blade and said second rudder blade.
A device for redirecting a jet stream flow created by a watercraft when in a body of water having a surface, wherein said watercraft also creates a displaced water flow and has a pump assembly, wherein said pump assembly has a deflector nozzle, wherein said deflector nozzle has a nozzle outlet, reverse gate pivotably connected to said nozzle, said device comprising:
- a first and second rudder blade, pivotally attached to said deflector nozzle such that said first and second rudder blades are approximately parallel to one another, wherein said first and second rudder blades have a lower position and an active position,
- a mount bracket connector connected between said first and second rudder blade,
- a down force regulator formed as one integral unit with said mount bracket connector,
- a first lift tab connected proximate said lower back edge of said first rudder blade,
- a second lift tab connected proximate said lower back edge of said second rudder blade, and
- wherein said displaced water flow acts on said first and second lift tabs to create an upward force on said first and second lift tabs.
A device for redirecting a jet stream flow created by a watercraft when in a body of water having a surface, wherein said watercraft also creates a displaced water flow and has a pump assembly, wherein said pump assembly has a deflector nozzle, wherein said deflector nozzle has a nozzle outlet, reverse gate pivotably connected to said nozzle, said device comprising:
- at least two rudder blades pivotally connected to said deflector nozzle, wherein said deflector nozzle has a torsion spring attached to at least one of said at least two rudder blades, a frame having:
- at least two mount brackets each having a first end and a second end,
- a mount bracket connector attached to said first end of said at least two mount brackets,
- a down force regulator integrated with said mount bracket connector, and
- at least two lift tabs attached to said second end of said at least two mount brackets,
- wherein said frame is fixed between said at least two rudder blades, such said at least two rudder blades are parallel to one another, and
- wherein said jet stream flow creates a downward force on said down force regulator when said at least two rudder blades are in a lowered position.
