Discover Seamless Navigation with the Simrad NAC-2 VRF Core Pack

Imagine gliding across open waters without constantly adjusting the helm— that's the freedom the Simrad NAC-2 VRF Core Pack delivers for boaters with vessels up to 33 feet. This all-in-one autopilot solution combines intelligent control algorithms with rugged marine-grade components, ensuring steady steering through choppy seas or calm bays. Whether you're out on an outboard fishing rig or an inboard cruiser, this pack transforms long voyages into effortless adventures, letting you focus on the horizon instead of the wheel.

Everything You Need in One Complete Kit

Skip the hassle of sourcing parts separately. This core pack arrives ready to integrate:

• NAC-2 Autopilot Computer: The smart core that processes heading data, controls drives, and adapts to real-world conditions like waves and wind shifts.
• Precision-9 Compass: A compact, solid-state sensor delivering precise heading, rate-of-turn, roll, and pitch data over NMEA 2000.
• N2k Backbone Starter Kit: Essential wiring including a power cable, 15-foot N2k cable, three T-connectors, and two terminators for plug-and-play network setup.

Standout Features That Set It Apart

• Certified NMEA 2000 Connectivity: Seamlessly links with Simrad chartplotters, radars, and other instruments for a unified onboard ecosystem.
• VRF Technology: Virtual Rudder Feedback eliminates the need for a physical feedback unit, simplifying installation on smaller boats while maintaining pinpoint accuracy.
• Robust Drive Compatibility: Handles low-current hydraulic pumps like the RPU80, mechanical drives such as the SD10, or solenoids up to 8A continuous—perfect for vessels under 10 meters.
• IPX7 Waterproof Rating: Survives splashes, sprays, and submersion, built tough for harsh marine environments.
• Heading Accuracy ±2°: After simple calibration, expect reliable performance even in dynamic conditions with 9-axis sensor fusion.

The NAC-2 Autopilot Computer: Your Vessel's Intelligent Helmsman

At the heart of the system, the NAC-2 employs advanced algorithms honed for diverse sea states. It interfaces effortlessly with heading sensors and drive units, outputting commands via 12/24V DC for solenoids or clutches. With a wide 9-31.2V DC input range, it powers reliably from your boat's battery bank. Compact at 7.1" x 2.2" and weighing just 1.3 lbs, it's easy to tuck away in tight console spaces. Splashproof IPX5 protection keeps it operational from -13°F to 131°F.

Precision-9 Compass: Accuracy Without the Complexity

This isn't your grandfather's fluxgate—it's a modern solid-state marvel using nine axes of motion data for superior heading and ROT outputs. Mount it on a bulkhead or up the mast with the adjustable bracket; calibration prompts guide you through setup in minutes. At IPX7, it shrugs off heavy rain, and its 0.5m compass-safe distance means fewer mounting headaches near speakers or motors. Low power draw (just 0.4W) won't strain your electronics.

N2k Starter Kit: Plug-and-Play Networking Made Simple

Get your NMEA 2000 backbone up in no time. The included kit provides all the Micro-C connectors and cabling needed to daisy-chain devices, ensuring fast, reliable data sharing across your Simrad suite.

Installation Insights for Smooth Setup

Boat owners rave about the NAC-2's straightforward install. Mount the computer in a dry spot, connect the N2k backbone, wire your drive unit, and pair the Precision-9 via the network. Use the VRF mode to bypass traditional rudder feedback—ideal for retrofits. Test in calm water first, then calibrate under way for optimal response. Pro tip: Position the compass away from magnetic interference for best results.

Why Boaters Trust This Autopilot Pack

For small to mid-size boats, the NAC-2 VRF Core Pack strikes the perfect balance of power, simplicity, and affordability. It reduces fatigue on extended trips, enhances safety with stable course-holding, and integrates with expanding Simrad networks. Backed by Simrad's reputation for durability, it's a smart upgrade that pays off in confidence on the water.
