Simrad NAC-3 VRF Core Pack 10m Plus is the trusted autopilot brain your yacht relies on for precise, hands-off helm control. Built around advanced control algorithms, this core pack manages steering decisions so you can focus on the voyage, confident that the system reacts to changing conditions with calm, predictable responses.

Designed for boats 10 meters (33 feet) and longer, the NAC-3 VRF Core Pack provides the essential electronics to operate a hydraulic or mechanical drive unit while seamlessly interfacing with your vessel’s heading sensors and rudder feedback systems. It’s the dependable backbone that translates steering intent into smooth, accurate coursekeeping across a broad range of weather and sea states.

Key capabilities that set it apart

• Powerful autopilot brain: Encapsulates robust control algorithms that govern heave, trim, and heading adjustments, delivering stable guidance in challenging conditions.
• High-current drive compatibility: Rated to operate high-current hydraulic drives, mechanical drives, and solenoid valves with a continuous current of 30 Amps (50 Amps peak), giving you the power needed for responsive steering even under load.
• Sensor and rudder integration: Interfaces with heading sensors and rudder feedback units to ensure precise heading maintenance and reliable ROT (rate of turn) behavior without drift.
• NMEA 2000 connectivity: Designed to integrate smoothly into existing NMEA 2000 networks, simplifying wiring and system synchronization across instruments and peripherals.
• Compact, dedicated core: The VRF Core Pack consolidates the autopilot’s core electronics in a compact package, optimized for dependable operation in marine environments.

This product is identified as 000-13338-001 and is purpose-built for serious offshore and coastal voyaging where consistent, repeatable autopilot performance matters. Please note: the NAC-3 Core Pack is shipped from a secure location as an online orders-only item, and is not sold directly in-store.

Why sailors choose the NAC-3 VRF Core Pack 10m Plus
