Core components for a Simrad Continuum autopilot system—just add a drive unit and controller.

This pack includes all of the core components you need to upgrade your boat with a Simrad Continuum autopilot system—just add a hydraulic pump or mechanical drive unit to suit your steering system, and choose a dedicated autopilot controller or Simrad multifunction display.

Designed for outboard and sterndrive vessels up to 35' in length, this pack includes the NAC-2 autopilot computer, Precision-9 solid-state compass, plus all necessary NMEA 2000 cables and connectors.

The NAC Autopilot Computer is the brains behind your Simrad autopilot system. It contains the electronics needed to operate a hydraulic steering pump or mechanical drive unit, while also interfacing with other components including heading sensors and rudder feedback units.

The NAC-2 was designed for boats up to 35' in length and is suitable for low-current pumps, mechanical drive units, or solenoid valves (eight amps continuous/16 amps peak).

Key Features

  • Reliable autopilot performance based on Simrad Continuum steering technology
  • Recommended for boats up to 35' in length
  • Output of 8A continuous, 16A peak
  • Clutch output (3A maximum)
  • Compatible with low-current drive pumps, mechanical drives, hydraulic linear drives, and solenoid valves
  • Virtual rudder feedback for simplified installation aboard outboard and sterndrive boats
  • Supports Simrad RF25 only
  • Plug-and-play connectors for easy installation
  • NMEA 2000 connectivity to heading sensors, rudder feedbacks, dedicated autopilot controllers, and multifunction displays. Does not network using the older NMEA 0183.

Standard Output: The NAC-2 Autopilot Computer is recommended for boats up to 10 metres (35 feet) in length. It delivers standard power output of up to eight amps continuous and 16 amps peak, plus a clutch output; this is suitable to operate low-current drive pumps including the Simrad RPU80, mechanical drives such as the Simrad SD10, hydraulic linear drives such as the HLD350, and solenoid valves.


Easy Installation
Plug-and-play connectors facilitate easy installation, minimising the wiring necessary to install your autopilot system. Industry-standard NMEA 2000® networking offers simple connectivity to heading sensors, rudder feedback units, autopilot controllers, and multifunction displays located anywhere on board.
