Simrad NAC-2 Autopilot Computer for Small Boats Up to 10m

The Simrad NAC-2 Autopilot Computer is the compact brain your small boat needs to achieve hands-off steering with minimal power draw. Built for vessels up to 10 meters (33 ft), this autopilot controller drives lightweight hydraulic and mechanical drives with precision, giving you steady, responsive wheel action across a variety of conditions.

Why the NAC-2 stands out

• Low-current efficiency tailored for weekend sailors and coastal cruisers who want reliable autopilot performance without draining precious battery capacity.
• Multiple drive compatibility supports small hydraulic and mechanical drives, hydraulic linear drives, and solenoid valves (8 A continuous, 12 A peak) for flexible, space-saving configurations.
• Plug & Play installation minimizes wiring hassles and speeds up setup, so you’re on course sooner and with less downtime.
• Advanced helm logic finely tunes wheel responses to hold course across a broad range of sea states, delivering predictable corrections and smooth steering feel.
• Seamless sensor integration communicates with heading sensors and rudder feedback units to maintain navigation continuity and accurate course corrections.

Versatile, reliable steering for intimate boats

Designed specifically for small vessels, the NAC-2 is the dependable autopilot core that coordinates drive output and sensor input without occupying valuable helm space. It’s ideal for coastal cruisers who want confident hands-off steering on long passages, weekend sailors maneuvering crowded harbors, and anglers who value steady, low-draw steering while focusing on fishing or navigation.

What makes it practical for real-world use

• Condition-tuned performance ensures the boat maintains a steady course whether you’re sailing in chop, in light chop, or negotiating gusty winds near shore.
• Flexible integration works with the boat’s existing helm hardware and control systems, enabling easy upgrades in older installations or new builds where space is at a premium.
• Energy-conscious operation minimizes electrical load at the helm, leaving more reserve power for essential electronics and lighting.
