Variant speed directional control mechanism for water-jet powered craft

摘要

The invention relates to an auxiliary appendage(s) to improve off plane steering response and maneuverability of water jet powered crafts. The invention utilizes the pump's water flow and rotates on a horizontal axis, parallel to the water. Utilizing surface tension, drag or mechanical control the device rotates up and down on the vertical plane. The device does not cause additional sheer or stresses on water jet thrust assemblies. The invention easily attaches to water jet powered craft dramatically improving the steering capability during off-plane maneuvering. Its unique design allows adjustable torsion loading, rotates on one or both sides and allows precise tuning for multiple crafts from personal watercraft to large water jet powered crafts. This device operates on either side of the discharge nozzle to increase low speed control until the speed increases to a (craft dependent) preset point and allow the device to tilt out of the water.
