Simrad NAC-3 VRF Core Pack - NAC-3, Precision-9 & N2k Starter Kit
Simrad NAC-3 VRF Core Pack - NAC-3, Precision-9 & N2k Starter Kit — Product description
Upgrade your vessel's navigation with the Simrad NAC-3 VRF Core Pack, a powerhouse bundle tailored for boats over 33 feet. This all-in-one kit combines the intelligent NAC-3 autopilot computer, the ultra-reliable Precision-9 compass, and an essential NMEA 2000 starter kit to deliver seamless, hands-free steering across choppy seas or calm waters. Whether you're cruising coastal waters or tackling offshore adventures, this setup minimizes crew fatigue and keeps you on course with precision that stands up to real-world marine demands.
Why Choose the NAC-3 Autopilot for Your Boat?
At the heart of this core pack is the NAC-3 autopilot computer, engineered as the command center for your steering system. It employs advanced control algorithms fine-tuned for diverse sea conditions, from glassy calms to rough swells. Unlike basic pilots, the NAC-3 handles high-current hydraulic pumps like the RPU160 or RPU300, mechanical drives such as the DD15, and solenoid valves—up to 30 amps continuous or 50 amps peak. Virtual Rudder Feedback (VRF) eliminates the need for a traditional rudder sensor, simplifying setup while maintaining pinpoint accuracy. It's built tough with IPX7 waterproofing, plastic construction for corrosion resistance, and compatibility with 12/24V systems, making it ideal for larger yachts and workboats.
Precision-9 Compass: Your Reliable Heading Source
The included Precision-9 compass revolutionizes heading data with solid-state 9-axis sensors that track heading, rate of turn, roll, and pitch over NMEA 2000. Achieving ±2° accuracy post-calibration, it outperforms traditional fluxgate compasses in dynamic environments. Mount it flexibly on bulkheads or masts with the adjustable bracket, and connect via a single cable for effortless integration. Its rugged IPX7 rating ensures it thrives in spray, rain, or submersion, providing stable inputs to your autopilot, radar, and chartplotters from Simrad, B&G, or Lowrance ecosystems.
N2k Starter Kit: Seamless Network Connectivity
Networking shouldn't be a hassle, and the N2k Backbone Starter Kit makes it simple. This kit supplies a power cable, 15-foot N2k cable, three T-connectors, and two terminators—everything needed to kickstart your NMEA 2000 backbone. Drop it in to link your NAC-3, Precision-9, and other marine electronics into a unified system, enabling shared data for smarter navigation decisions.
Key Features That Set It Apart
- High-current drive compatibility for robust hydraulic and mechanical steering.
- Solid-state sensors for maintenance-free, drift-resistant performance.
- Full NMEA 2000 and NMEA 0183 support for broad device integration.
- NFU (Non-Follow-Up) levers and mode selection for intuitive manual override.
- Alarm outputs and engage signals for safety and clutch control.
- Compact dimensions (8.31" x 7.72" x 2.58") with grommet cable entry for clean installs.
Real-World Performance and Installation Insights
Boaters rave about the NAC-3's ability to hold course tighter than competitors during beam seas or following swells, thanks to its sophisticated adaptive steering. Installation is straightforward: secure the NAC-3 to a bulkhead, calibrate the Precision-9 in calm conditions, and wire up the N2k backbone. Pro tip: Position the compass away from ferrous metals and magnetic influences for optimal calibration. Operating from 0°C to +55°C, it shrugs off harsh environments while drawing minimal power (1 LEN on N2k). Pair it with Simrad multifunction displays for intuitive autopilot controls right from your helm.
Technical Specifications at a Glance
Delivered complete with the NAC-3 computer, Precision-9 compass, and N2k starter kit, this VRF core pack equips you for confident, efficient voyages. It's not just gear—it's the reliable partner that lets you focus on the horizon.
