Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 89 words
A stabilizer system for a boat comprising a pair of nozzles mounted to extend below the boat with one of said nozzles positioned adjacent the front of the boat and the other positioned adjacent the rear of the boat, each of said nozzles being provided with an outlet portion extending substantially parallel to the plane of the boat, means for pumping water through said nozzles, means for selectively rotating said nozzles about vertical axis, and means automatically retracting said nozzles into said boat upon nonoperation of said pumping means.
Claim 2
Dependent Claim 89 words
A stabilizer system for a boat comprising a pair of nozzles mounted to extend below the boat with one of said nozzles positioned adjacent the front of the boat and the other positioned adjacent the rear of the boat, each of said nozzles being provided with an outlet portion extending substantially parallel to the plane of the boat, means for pumping water through said nozzles, means for selectively rotating said nozzles about vertical axis, and means automatically retracting said nozzles into said boat upon nonoperation of said pumping means.
Claim 3
Dependent Claim 20 words
The stabilizer system as defined in claim 1 and in which said nozzles extend through the bottom of the boat.
Claim 4
Dependent Claim 22 words
The stabilizer system as defined in claim 1 and in which said nozzles are positioned along the longitudinal centerline of said boat.
Claim 5
Dependent Claim 41 words
The stabilizer system as defined in claim 1 and in which said last mentioned means comprises said nozzles being hingedly mounted to said boat, and a counterweight attached to each of said nozzles to urge said nozzles to be pivoted upwardly.
Claim 6
Dependent Claim 16 words
The stabilizer system as defined in claim 1 and in which said nozzles are rotatably 360°.
Claim 7
Dependent Claim 48 words
The stabilizer system as defined in claim 1 and in which said rotating means comprises a pulley mounted to each of said nozzles, a steering wheel, and means connecting said steering wheel to said pulleys, whereby rotation of said steering wheel produces a corresponding rotation of said nozzles.
Claim 8
Dependent Claim 17 words
The stabilizer as defined in claim 1 and including means for selectively proportioning flow between said nozzles.
Claim 9
Dependent Claim 179 words
A stabilizer system for a boat comprising a pair of nozzles mounted to extend below the boat with one of the nozzles positioned adjacent the front of the boat and the other positioned adjacent the rear of the boat, each of said nozzles being provided with an outlet portion disposed below the boat extending substantially parallel to the plane of the boat, means for pumping water through said nozzles, said pumping means including an inlet disposed intermediate said nozzles, means mounting said nozzles to rotate 360° about a vertical axis, means operable to selectively produce simultaneous rotation of said nozzles and means disposed intermediate said pumping means and said nozzles for selectively proportioning flow between said nozzles said proportioning means comprising a conduit leading from said pumping means, a metering valve connected to said pumping means by said conduit, conduits connecting said metering valve and said nozzles, said metering valve being operable to maintain flow through at least one of said nozzles at all positions thereof and being thereby operable to proportion the flow of water through said nozzles.
Claim 10
Dependent Claim 179 words
A stabilizer system for a boat comprising a pair of nozzles mounted to extend below the boat with one of the nozzles positioned adjacent the front of the boat and the other positioned adjacent the rear of the boat, each of said nozzles being provided with an outlet portion disposed below the boat extending substantially parallel to the plane of the boat, means for pumping water through said nozzles, said pumping means including an inlet disposed intermediate said nozzles, means mounting said nozzles to rotate 360° about a vertical axis, means operable to selectively produce simultaneous rotation of said nozzles and means disposed intermediate said pumping means and said nozzles for selectively proportioning flow between said nozzles said proportioning means comprising a conduit leading from said pumping means, a metering valve connected to said pumping means by said conduit, conduits connecting said metering valve and said nozzles, said metering valve being operable to maintain flow through at least one of said nozzles at all positions thereof and being thereby operable to proportion the flow of water through said nozzles.
