NAC-2 Autopilot Computer: The NAC-2 serves as the central processing unit for your autopilot system, containing all electronics needed to operate hydraulic steering pumps or mechanical drive units. It interfaces seamlessly with heading sensors and rudder feedback units to deliver precise steering control. The standard power output supports operation of low-current drive pumps like the Simrad RPU80, mechanical drives such as the SD10, hydraulic linear drives like the HLD350, and solenoid valves.
Simrad Continuum Technology: Built on over 60 years of autopilot development and ongoing research at Simrad's Norwegian facility, the Continuum steering algorithm represents decades of marine expertise. This intelligent software continuously analyzes vessel movement and conditions to make optimal steering decisions, providing a smart pilot you can trust in varying sea conditions.
RF25N Rudder Feedback Unit: The included RF25N sensor connects to your rudder via mechanical linkage and continuously reports actual rudder position to the autopilot computer. This real-time feedback allows the Continuum algorithm to make precise steering corrections. The RF25N is ideal for inboard engine installations and larger vessels where accurate rudder position data is essential.
Precision-9 Solid-State Compass: This advanced heading sensor provides accurate directional data to your autopilot system with no moving parts for reliable, maintenance-free operation. The solid-state design delivers precise heading information in all conditions.
Installation: Plug-and-play connectors and industry-standard NMEA 2000® networking simplify installation, minimizing wiring complexity. All necessary cables and connectors are included in the pack. The system connects easily to autopilot controllers and multifunction displays located anywhere on board. For outboard and sterndrive boats, Virtual Rudder Feedback technology can eliminate the need for physical rudder feedback installation, reducing system complexity where mechanical constraints make traditional feedback units impractical.
