NAC-3 Autopilot Core Pack with SteadySteer - Includes SteadySteer Flow Switch,
NAC-3, Precision-9, RF25N & N2k Starter Kit
Comprising of the high-current NAC-3 autopilot computer, Precision-9 compass,
RF-25 rudder feedback unit & N2k Starter Kit.
The NAC-3 Autopilot Computer is the brains behind your autopilot system. NAC-3
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-3 was
designed for boats 10M (33') or greater in length and is rated to operate
high-current hydraulic drives, mechanical drive units, and solenoid valves with
a current rating of 30 Amps continuous (50 Amps peak).
SteadySteer Flow Switch
Navigate safely with SteadySteer, a new functionality for autopilot systems that
allows boaters to take immediate, manual control of the vessel through turns
without having to disengage the autopilot. Coming out of turns, SteadySteer
automatically reengages the autopilot once a new heading is established.
Control the autopilot with the helm
SteadySteer automatically disengages the autopilot when you turn the vessel
manually and then reengages the autopilot when you have established a new
heading. No key-presses, no alarms – just turn the helm.
Less distractions – Just drive
No need to look at a display or push buttons to change course, merely point the
bow to your destination.
SteadySteer is compatible with NAC-2, NAC-3 autopilot computers (sw version
1.1.01.00 and newer), AP44, IS42, and AP48 (sw version 57.3.163 and newer) and
Simrad multifunction displays (sw version 20.2 and newer).
Suitable for vessels with hydraulic steering, SteadySteer will be available to
purchase alongside existing Simrad autopilot systems.
The Precision-9 Compass. Outputs Heading (20 hZ), Rate Of Turn (20 hZ), roll,
and pitch (10 hZ) over the NMEA 2000® network.
