The Simrad NAC-3 VRF Core Pack delivers everything you need to build a professional-grade autopilot system on larger vessels. Designed for outboard and sterndrive boats 35 feet and longer, this comprehensive package includes the high-current NAC-3 autopilot computer, Precision-9 solid-state compass, and all necessary NMEA 2000® cables and connectors. Simply add a compatible hydraulic pump or mechanical drive unit for your steering system, plus your choice of dedicated autopilot controller or Simrad multifunction display.
NAC-3 Autopilot Computer: The intelligent core of your steering system, the NAC-3 processes data from heading sensors and rudder feedback to deliver precise control. Built for vessels 35 feet and above, it provides high-current output rated at 30 amps continuous and 50 amps peak, with an additional 3-amp clutch output. This robust capacity supports high-current hydraulic pumps like the Simrad RPU160 and RPU300, mechanical drives such as the DD15, hydraulic linear drives including the HLD2000 series, and solenoid valves.
Key Features:
- Simrad Continuum steering technology with over 60 years of autopilot development
- High-current output: 30 amps continuous, 50 amps peak capability
- Virtual Rudder Feedback (VRF) technology eliminates separate feedback unit on outboard/sterndrive installations
- Compatible with Simrad RF25 and RF300 rudder feedback units for inboard applications
- Precision-9 solid-state compass for accurate heading data
- NMEA 2000® connectivity for seamless system integration
- Complete installation kit with cables and connectors included
Simplified Installation with VRF: The innovative Virtual Rudder Feedback technology reduces system complexity and cost by eliminating the need for a mechanical rudder feedback sensor on outboard and sterndrive vessels. For inboard installations or specialized applications, the NAC-3 supports both NMEA 2000® connected RF25 units and variable frequency output sensors like the RF300.
Continuum Steering Intelligence: Every steering decision is powered by Simrad's proprietary Continuum algorithm, developed at the company's Norwegian autopilot research facility. This advanced software represents decades of marine autopilot expertise, delivering smart, reliable steering performance you can trust in all conditions.
