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.
