NAC-2 Autopilot Computer: Compact and Reliable Autopilot Core
The NAC-2 is a versatile autopilot computer ideal for boats up to 10 meters (35 feet) in length. It provides dependable, low-current steering control with straightforward integration into modern marine electronics systems.
Plug-and-Play Installation
Enjoy hassle-free setup with plug-and-play connectors that significantly reduce wiring requirements. Industry-standard NMEA 2000® networking enables quick connections to heading sensors, rudder feedback units, dedicated autopilot controllers, and multifunction displays positioned anywhere on board.
Reliable Low-Current Drive Support
Engineered for smaller vessels, the NAC-2 reliably powers a range of drive systems, including:
- Low-current reversible pumps like the Simrad RPU80
- Mechanical drives such as the Simrad SD10
- Hydraulic linear rams, including the HLD350 series
- Solenoid-controlled valves
This ensures smooth, precise autopilot performance without overwhelming power demands.
Virtual Rudder Feedback for Simplified Systems
Simrad's innovative Virtual Rudder Feedback (VRF) technology eliminates the need for a separate physical rudder feedback sensor on most outboard and sterndrive (I/O) planing-hull boats. This smart feature lowers installation cost and complexity while delivering accurate steering response—especially useful where mechanical constraints make traditional sensors difficult to fit.
For vessels requiring a dedicated sensor, the NAC-2 fully supports SimNet or NMEA 2000® connected units like the Simrad RF25, as well as standard resistive rudder feedback sensors.
Choose the Simrad NAC-2 for an efficient, easy-to-install autopilot solution that combines proven reliability with modern convenience on mid-sized powerboats.
