SI-TEX SP-120 System w/Rudder Feedback - No Drive Unit

The SI-TEX SP-120 System w/Rudder Feedback is a precision marine autopilot designed for cruising sailboats and small to mid-sized powerboats that demand reliable hands-free steering in variable sea conditions. This system is ideal for boaters planning a staged installation, as it is supplied without a drive unit and can be paired with existing or separately sourced steering actuators.

Built by SI-TEX, a trusted name in marine electronics, the SP-120 system integrates rudder feedback technology to maintain accurate course-keeping even as wind, current, and sea state shift beneath your hull. The rudder feedback feature continuously monitors your vessel's actual rudder position and feeds that data back to the autopilot processor, enabling closed-loop steering corrections that hold course with minimal deviation.

Cruising sailors and offshore boaters will find the rudder feedback technology especially valuable in rough water or when sailing downwind, where traditional heading-hold systems can lag or overshoot corrections. The modular design allows for flexibility in system configuration, making it a cost-effective solution for experienced boaters and installers.
