A steering mechanism for an add-on module is provided including a handlebar connected to a headset that is rotatable. The rotating headset is connected to a pair of arms each of which is connected to a connecting line. The two connecting lines are connected to a pivoting nozzle. The nozzle is pivotably and detachably attached to the tail end of a jet board.

There is disclosed a watercraft paddle apparatus operable by a user's legs and feet. In an embodiment, the watercraft paddle apparatus comprises a pair of rails positioned side-by-side and mountable to a watercraft, each rail configured to slidably receive a pedal mechanism adapted to slide back and forth along each rail. Each pedal mechanism includes a downwardly extendable paddle adapted to engage a water surface on which the watercraft is floating during a backward stride and to lift from the water surface on a forward stride, whereby a user can operate the pedal mechanism in each rail using an alternating walking or skiing motion. In an embodiment, each pedal mechanism is supported laterally by a front axle with a pair of wheels on either end of the front axle engaging the parallel rails. In another embodiment, each pedal mechanism is attached, via a rotatable joint, to a rear axle with a pair of wheels on either end of the rear axle engaging the same parallel rails as the front axle, whereby, the rotatable joint allows each pedal to be angled through a range of motion in order to support a user's foot throughout a stride.

In a first step of a watercraft control method, a command signal to activate an automatic cruise function is received. In a second step, a target vessel velocity of a watercraft is set. In a third step, an actual vessel velocity of the watercraft is obtained. In a fourth step, a command signal is generated that is a signal to perform an automatic cruise control to control a thrust of the watercraft such that a difference between the target vessel velocity and the actual vessel velocity falls in a predetermined range of values. In a fifth step, it is determined whether or not a predetermined interruption condition has been established. In a sixth step, a command signal is generated that is a signal to perform the automatic cruise control with the thrust having a different magnitude from the thrust to be generated under normal circumstances without establishment of the interruption condition when the interruption condition has been established.

An electric inboard motor for a boat, includes a main body, a motor, a motor controller, a motor mounting base, a paddle, a paddle shall, a speed-adjusting handle assembly and a main body overturning locking mechanism. The speed-adjusting handle assembly further includes a speed-adjusting handle spindle, an axle sleeve, a handle sleeve, a button, a spring and at stop, block; one end of a handle shell is fixedly connected with the stop block, and the handle sleeve abuts against a stepped face of the stop block, the speed-adjusting handle spindle is connected with the handle shell in a rotation manner, the speed-adjusting handle spindle is connected with the axle sleeve through a first pin, the axle sleeve is fixedly connected with the button, and the axle sleeve is connected with the stop block in a rotation manner and connected with the handle sleeve.

An amphibious vehicle having a smart marine throttle which, when enabled, will control the power to right and left propulsors. The vehicle will then be able to automatically follow a course to a predetermined destination while overcoming the effect of wind, water current and wave action. The invention also includes a method for autopiloting a marine vessel.

A water bike has a frame supported on first and second spaced apart pontoons or similar floatation elements. Pedals are attached to cranks on a front sprocket rotatably supported on the frame. A chain or belt extends around the front sprocket and around a rear sprocket on a gearbox. An outdrive is supported on the gearbox and pivotal about a vertical axis relative to the gearbox. The combined outdrive and gearbox are pivotable about a horizontal axis relative to the frame. A propeller on the outdrive is mechanically linked to a first gear in the gearbox, with the first gear meshing with a second gear attached to the rear sprocket. A steering bar is pivotally attached to the frame. A steering linkage connects the steering bar to the outdrive, for pivoting the outdrive to steer the water bike.

A steering control system for a watercraft includes a pivoting steering tiller manually operated and operatively connected to a direction changing member acting on or into the water, such as a rudder blade or an outboard motor; and a system locking the steering tiller in the steering position, which can be activated for keeping the tiller in a predetermined pivoting position and deactivated for allowing the tiller to be moved in a pivoting position to carry out a change in direction. According to the invention the locking system is switchable by way of switching actuators that are controlled by a control member provided on the arm.

A watercraft is provided with a watercraft body and a storage container. The watercraft body includes a hull and a deck. The deck is provided on the hull. The storage container is attached to the watercraft body. The storage container includes an access opening and an annular sidewall. The access opening opens upward relative to the deck. The annular sidewall has an upper end, a lower end and an interior storage space between the upper end and the lower end. The lower end of the annular sidewall defines a bottom opening with a cross sectional area that is larger than a cross sectional area of the upper end of the annular sidewall.
