NAC-3 VRF Core Pack

SKU: 000-13338-001

This pack includes the core components you need to upgrade your boat with a Continuum autopilot system, designed for outboard and sterndrive vessels greater than 10 metres (35 feet) in length. Just add a drive unit to suit your steering system, and choose a Simrad autopilot controller or multifunction display.

Key Features

  • Core autopilot system components – just add a drive unit and controller
  • Ideal for outboard and I/O boats above 10 metres (35 feet) in length
  • Compatible with high-current drive pumps, mechanical drives, hydraulic linear drives, and solenoid valves
  • Take control with the B&G Triton2 controller, Triton2 display, Simrad AP44 Autopilot Controller, IS42 display and OP12 keypad, or a networked multifunction display
  • Virtual Rudder Feedback eliminates the need to install a mechanical rudder feedback unit
  • Easy setup with automatic tuning and compass calibration

Product details

NAC-3 Autopilot Core Pack

This pack includes the B&G/ Simrad NAC-3 autopilot computer, Precision-9 solid-state compass, plus all cabling and connectors required to build an NMEA 2000® network backbone or connect your autopilot system to an existing NMEA 2000® network. This pack is recommended for outboard and sterndrive boats greater than 10 metres (35 feet) in length, and is suitable for use with high-current drive pumps including the B&G/ Simrad RPU160 and RPU300, mechanical drives such as the B&G/ Simrad DD15, hydraulic linear drives such as the HLD2000 series, and solenoid valves.

Multiple Control Options

Choose from a range of dedicated autopilot controllers, or control your autopilot from your existing B&G/ Simrad multifunction display. Install extra autopilot stations, ideal for dual-helm vessels, or add the B&G/ Simrad WR10 wireless remote for instant steering and autopilot control from anywhere on board.

Easy Installation and Setup

B&G/ Simrad Virtual Rudder Feedback (VRF) technology eliminates the need to install a mechanical rudder feedback unit aboard outboard and sterndrive (inboard/outboard) boats. VRF technology greatly simplifies autopilot installation, while delivering uncompromising Continuum steering performance. Industry-standard NMEA 2000® networking and NMEA 0183® input allow simple connectivity to sensors, autopilot controllers, and multifunction displays located anywhere on board. Auto-tuning simplifies setup and ensures optimal steering performance, while automatic compass calibration continuously improves heading accuracy as you travel.

Minimum product requirements

Requires a hydraulic steering pump or mechanical drive unit, and a compatible autopilot controller or networked multifunction display.
