NAC-2 VRF Core Pack – NAC-2, Precision-9 & N2k Starter Kit

Comprising of the high-current NAC-2 autopilot computer, Precision-9 compass and N2k Starter Kit.

The NAC-2 Autopilot Computer is the brains behind your autopilot system. NAC-2 contains the control algorithms developed to helm a yacht across a broad range of weather conditions and sea-states, alongside the electronics needed to operate a hydraulic 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 10M (33′) in length and is suitable for low-current hydraulic drives, mechanical drives, or solenoid valves with a current rating of 8 Amps continuous (12 Amps peak).

Precision-9 Compass

The Precision-9 Compass supplies heading and rate-of-turn information to Simrad, B & G and Lowrance autopilot, radar and navigation systems. Based on reliable solid-state sensor technology, this compact compass offers easy installation aboard any vessel.
