Abstract
Methods and arrangements to rapidly adjust the trim of a watercraft are disclosed. More specifically, embodiments comprise a sensor to quickly detect changes in the trim angle of a watercraft and a driver adapted to effect rapid changes in the trim angle. For example, many embodiments include large hydraulic pumps and hydraulic connections to adjust the angle of a trim adjuster such as the angle of trim tabs, an outboard motor, or a stern drive. Some embodiments implement high torque electric motors or high capacity pneumatic systems. The drivers may, for example, effect changes in the angle of the trim adjuster within two seconds. In one embodiment, the driver may effect a change in the trim angle within one second or less.
Claims13
A watercraft capable of rapid adjustment of a trim angle for the watercraft in a body of water, the watercraft comprising:
- a hull having a motor to accelerate the watercraft with respect to the body of the water;
- a trim adjuster having positions, wherein the positions are associated with adjustments for the trim angle of the watercraft;
- a driver coupled with the trim adjuster to apply a force to the trim adjuster, the application of the force to reorient the trim adjuster into a position of the positions, wherein the driver is sized to respond to the sensor by repositioning the trim adjuster within five seconds of generation of a sensor signal;
- a sensor to output the sensor signal related to the trim angle of the watercraft;
- and
- a control arm coupled with the sensor, wherein the control arm is adapted to modify a tilt of the sensor, wherein modifying the tilt of the sensor adjusts the sensor signal that is related to the trim angle.
A watercraft capable of rapid adjustment of a trim angle for the watercraft in a body of water, the watercraft comprising:
- a hull having a motor to accelerate the watercraft with respect to the body of the water;
- a trim adjuster having positions, wherein the positions are associated with adjustments for the trim angle of the watercraft;
- a driver coupled with the trim adjuster to apply a force to the trim adjuster, the application of the force to reorient the trim adjuster into a position of the positions, wherein the driver is sized to respond to the sensor by repositioning the trim adjuster within five seconds of generation of a sensor signal;
- a sensor to output the sensor signal related to the trim angle of the watercraft,
- wherein the sensor comprises:
- a joint to couple with the watercraft, having an axis;
- a member coupled with the joint, the member to be in contact with the body of the water, wherein the member is to rotate with respect to the axis of the joint in response to a change of trim angle of the watercraft, based upon a force applied to the member, the force being responsive to a flow of the water contacting the member as the watercraft moves with respect to the body of the water;
- and
- a measurement device to couple with the joint, wherein the measurement device is to produce the sensor signal in response to a rotation of the member with respect to the axis of the joint, wherein the sensor signal is indicative of a position of the rotation.
