NAC-2 Autopilot Core Pack - NAC-2, Precision-9, RF25N & N2k Starter Kit 
 
Comprising of the high-current NAC-2 autopilot computer, Precision-9 compass and 
RF-25 rudder feedback unit ideal for smaller vessels, designed to run small 
hydraulic drives and mechanical drives for vessels up to 10M (33') in length. 
 
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).
