Simrad NAC-2 VRF Core Pack for up to 10m Yachts and Boats

Simrad NAC-2 VRF Core Pack is the compact autopilot brain you’ve been waiting for on boats up to 10 metres (33 feet). This integrated package combines the NAC-2 Autopilot Computer with a precise, solid‑state heading source to deliver reliable, hands‑off steering across a broad range of weather conditions and sea states. Built for small yachts and workboats, it provides the dependable control you need when the helm is busy or when conditions tighten.

At the heart of the system, the NAC-2 VRF Core Pack houses advanced control algorithms that actively manage a hydraulic, mechanical, or solenoid‑valve drive unit. Whether you’re dialing in a steady course in a chop, or steering through gusty winds and rolling seas, the NAC-2 processes feedback from rudder position and heading sensors to keep your vessel on course with smooth, responsive adjustments. It’s designed for drives drawing up to 8 A continuous (12 A peak), making it compatible with a range of common on‑board steering configurations.

The Core Pack also incorporates the Precision‑9 Compass, providing heading and rate‑of‑turn (ROT) data to Simrad, B&G, and Lowrance autopilot and navigation systems. This compact, IPX7 waterproof unit relies on robust solid‑state sensors and 9‑axis motion data to deliver heading accuracy within about ±2 degrees after calibration. An easily adjustable mounting bracket supports bulkhead or up‑mast installation, giving you flexible, quick integration into your boat’s layout. The system communicates over a single NMEA 2000 backbone for simple, reliable connectivity.

Key benefits you’ll notice on the water:

• Consistent course‑keeping across variable seas and wind, reducing helm workload and fatigue.
• Broad drive compatibility with low‑current hydraulic or mechanical systems and solenoids up to 8 A continuous, expanding your retrofit options.
• Integrated heading source via the Precision‑9 Compass, ensuring accurate ROT and heading data for more predictable autopilot performance.
• Easy installation with a single NMEA 2000 connection, minimizing wiring complexity and setup time.
• Rugged, reliable in demanding conditions with IPX7 protection and solid‑state sensor technology designed for marine environments.

What’s included and how it helps you install

• NAC-2 Autopilot Computer—the brain that runs the VRF control algorithms.
• Precision‑9 Compass—the accurate heading reference used by the autopilot and compatible networks.
• Installation and wiring kit with connectors designed for a clean, reliable NMEA 2000 network.
• Compact, rugged housing and mounting options that suit small helm stations and compact pilot rooms.

Who it’s for and practical applications

Ideal for owners of small sailboats and powerboats who want confident, automatic steering without a bulky, complex retrofit. It’s a practical upgrade for coastal cruisers, day sailors, and boaters who navigate in varied conditions and want reduced workload on long passages or busy marina maneuvers. Because the system is designed for common drive types and uses a streamlined NMEA 2000 interface, it fits a wide range of existing steering configurations without extensive rework.
