The Simrad NAC-3 Core Pack Autopilot Computer is the brains behind your yacht’s steering system, delivering intelligent, reliable control that keeps your course with calm precision. Built for rudder-steered vessels over 10 meters (35 feet), this all‑in‑one autopilot solution is ready to integrate with a wide range of drives and a full NMEA 2000 network backbone.

• NAC-3 Autopilot Core – the central processing unit that runs steering algorithms, waypoint navigation, and course‑keeping logic with fast, dependable performance.
• RF25N rudder feedback unit – real‑time feedback on rudder position so commands are translated into precise, predictable movements.
• Precision-9 solid-state compass – a robust heading reference with low drift to stabilize navigation data even in challenging conditions.
• Includes all cabling and connectors required to build an NMEA 2000 network backbone or to connect to an existing marine network.

Designed to work seamlessly with a variety of propulsion and control options, the NAC-3 Core Pack is compatible with high‑current drive pumps (such as the RPU160 and RPU300), mechanical drives like the DD15, hydraulic drives in the HLD2000 series, and solenoid valve systems. This flexibility makes it a versatile upgrade for cruising boats, offshore passagemakers, and tournament-ready racers alike.

Why this core pack matters

• Effortless installation with everything needed to wire into a single, cohesive NMEA 2000 network—fewer loose cables and fewer headaches during setup.
• Enhanced reliability with a solid-state compass and precise rudder feedback that reduce drift and improve course stability—crucial for long passages and tight maneuvers.
