摘要： A watercraft is disclosed that includes a hull having port and starboard sides and a propulsion system that generates a stream of pressurized water through a nozzle. A helm operatively connects to the nozzle, whereby turning the helm turns the nozzle. At least one rudder connects to either or both of the port or starboard sides. The rudder is capable of pivoting inwardly and outwardly and can also be moved upwardly and downwardly with respect to the side to which it is connected. The rudder is located a certain distance from the respective side of the hull, which allows the rudder to utilize its inner and outer surfaces to assist in steering the watercraft by deflecting water flowing thereacross. Also, a linking element can connect the nozzle to the rudder. An off-power steering system is also disclosed.

摘要： The invention discloses a retractable rudder device attached to the water jet nozzle of a watercraft. In a non-deployed condition, the rudders are latched in position and completely out of the water stream underneath the craft. When deployed, two rudders aligned with the axis of the steering nozzle, are rotated into position via springs and cables. The rudders pivot independently of each other, and will retract if contact with an underwater object is made or the craft is beached. A cable system connected to a control unit lowers the rudders into the deploy position. The cable system is actuated by a hydraulic cylinder using fluid pressure from the jet pump. The deployment rate can be varied by altering the fluid pressure in the hydraulic cylinder, and is a function of boat speed. Deployment of the retractable rudder system is determined by an electronic control system. Input variables such as steering rates, jet pump pressure, throttle position, engine operation, immersion of the craft in the water determine if the rudder system is deployed. An anticipatory steering module is included in the controller to provide dynamic steering conditions under which the rudder system is deployed prior to full lock.

摘要翻译： 本发明公开了一种连接在船舶的喷水嘴上的伸缩方向舵装置。 在未部署的情况下，方向舵被锁定在位置并完全离开工艺下方的水流。 当部署时，与转向喷嘴的轴线对准的两个方向舵通过弹簧和电缆旋转到位。 方向舵彼此独立枢转，并且如果与水下物体接触或者船只被接触，则它将缩回。 连接到控制单元的电缆系统将方向舵降低到展开位置。 电缆系统由使用来自喷射泵的流体压力的液压缸致动。 通过改变液压缸中的流体压力可以改变部署速率，并且是船速度的函数。 可伸缩舵系统的部署由电子控制系统确定。 输入变量，如转向率，喷射泵压力，节气门位置，发动机操作，将工艺浸入水中确定舵系统是否部署。 控制器中包括一个预期的转向模块，以提供动态转向条件，在完全锁定之前部署方向舵系统。

摘要： The invention relates to an auxiliary system for providing positive steering to marine crafts using jet propulsion systems, typically personal jet driven watercrafts such as jet boats and jet skis. In one embodiment, it includes, among other features, a combination of keel members attached to a stern section of a hull. The keels are interconnected using tie rods to the directional steering drive assembly. In other embodiments, the keels are instead attached directly to the directional nozzle or integrally made with the nozzle, and where a hood is included in the directional nozzle assembly, notches may be included in the keels to allow for full operation of the hood into its lowest position.

摘要： A control mechanism for a watercraft includes a selectively movable flap connected to an actuator, which moves the flap into and out of the flow of water to affect steering, deceleration and trimming. The flap is recessed with respect to the lower surface of the hull so that it does not create drag at high speeds. The flap may be a portion of the ride plate, may be disposed in a recess in the bottom of the hull, or may be disposed on the stern above the bottom of the hull.
