NAC-2 VRF Core Pack: Comprising of the low-current NAC-2 autopilot computer and Precision-9 compass. The low-current NAC-2 autopilot computer is ideal for smaller vessels, designed to run small hydraulic drives and mechanical drives for vessels up to 10 metres (33 feet) in length. Also provides solenoid output. Output of 8 amps continuous, 16 amps peak. Clutch output (3 amps maximum). Virtual rudder feedback for simplified installation aboard outboard and sterndrive (inboard/outboard) boats. Supports Simrad RF25 rudder feedback units. NMEA 2000® connectivity to heading sensors, rudder feedbacks, dedicated autopilot controllers, and multifunction displays
Continuum steering technology
Every Simrad steering innovation builds upon a legacy encompassing over sixty years of autopilot development, which continues today at Simrad Yachting’s autopilot research hub in Norway. This legacy is exemplified by the Continuum algorithm: the software that drives Simrad steering technology. Continuum brings all those years of research and on-water experience to your helm, for a smart pilot you can trust to take the wheel.
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 B&G, Simrad RPU80, mechanical drives such as the B&G, Simrad SD10, hydraulic linear drives such as the T0, and solenoid valves.
Virtual Rudder Feedback
Simrad Virtual Rudder Feedback (VRF) technology eliminates the need to install a separate rudder feedback unit aboard outboard and sterndrive (inboard/outboard) boats. This reduces overall autopilot system cost and complexity, and is ideal where a feedback unit is impractical due to mechanical constraints.
Rudder Feedback Units
Rudder feedback units are sensors that connect to your rudder via a mechanical linkage and continuously report actual rudder position to your autopilot computer – allowing the Simrad Continuum steering algorithm to make the best-informed steering decisions possible. These sensors are typically used on boats with inboard engines, on larger vessels, and in special applications where Virtual Rudder Feedback may not be suitable. The NAC-2 supports SimNet or NMEA 2000® connected B&G, Simrad RF25 feedback units, and resistive rudder feedback sensors.
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.

NMEA 2000® Heading & ROT Output
With NMEA 2000® output, the Simrad Precision-9 Compass provides heading, Rate Of Turn (ROT), pitch and roll information to connected equipment including autopilots, radar, multifunction displays, and other navigational systems.
Solid-State Sensor Technology
The Precision-9 Compass incorporates a sophisticated solid-state sensor array based on MEMS technology. This high-precision array measures motion on nine separate axes in order to calculate the most accurate heading and rate-of-turn information possible, avoiding many common limitations of conventional fluxgate electronic compasses and delivering heading accuracy of ±2 degrees after calibration.
Mount Almost Anywhere
An easily adjustable mounting bracket allows the Precision-9 Compass to be installed on any vessel, in almost any location. The compass may also be mounted directly to any flat surface and, with an IPX7 waterproof rating, external up-mast installation is possible on steel hulled vessels to avoid magnetic interference. Installation is further simplified by NMEA 2000® connectivity, with a single cable carrying both power and data.
