Simrad NAC-2 VRF Virtual Rudder Feedback Core Pack

Description

Configure a compatible hydraulic or steer-by-wire outboard autopilot system with the Simrad NAC-2 VRF Virtual Rudder Feedback Core Pack. The package includes a NAC-2 course computer, Precision-9 nine-axis solid-state AHRS, and NMEA 2000 starter kit. It supports planing and displacement powerboat hulls and works with hydraulic steering or compatible steer-by-wire outboards, while Virtual Rudder Feedback is the stated dockside setup method.

The NAC-2 supports hydraulic cylinders up to 250 cc, or 15.2 cubic inches, and provides 8A continuous output with a 16A intermittent peak. It runs on 12V or 24V DC and has an IPX5 enclosure rating. Combined computer and sensor weight is 1.2 kg, or 2.6 lb. Drive selection, hydraulic cylinder volume, vessel steering arrangement, and NMEA 2000 network planning must be confirmed before installation.

Key Specifications of the Simrad NAC-2 VRF Virtual Rudder Feedback Core Pack

• The pack includes a NAC-2 course computer, Precision-9 nine-axis AHRS, and NMEA 2000 starter kit for autopilot integration.
• Hydraulic steering and compatible steer-by-wire outboards can use the pack when paired with an appropriate drive and vessel system.
• Hydraulic-cylinder capacity is specified up to 250 cc, or 15.2 cubic inches, requiring accurate cylinder-volume verification before selection.
• The NAC-2 provides 8A continuous drive output with a 16A intermittent peak for compatible low-current autopilot drive requirements.
• A 12V or 24V DC supply supports the core pack, while full locked-loop load can reach 20A intermittently.
• The Precision-9 uses a nine-axis solid-state AHRS, providing the documented heading and attitude-sensor component for the system.
• Virtual Rudder Feedback uses a dockside wizard configuration, removing a physical feedback sensor only in compatible installations.

System Integration and Drive Selection

This Simrad core pack does not include a steering drive, display, hydraulic pump, or complete autopilot installation. The NAC-2, Precision-9 sensor, and NMEA 2000 starter kit form the central course-computer and heading-sensor components. A compatible drive, control display, steering system, electrical circuit, and network architecture must be selected separately.

Continuum Steering Technology, Smart Turn patterns, and NoDrift target tracking are stated functions of the compatible system. The Precision-9 heading data is specified at plus or minus 1.0 degrees static and plus or minus 2.0 degrees during dynamic roll and pitch tracking. Actual steering results depend on the entire installed autopilot and vessel steering configuration.

Why Choose the Simrad NAC-2 VRF Virtual Rudder Feedback Core Pack

The Simrad NAC-2 VRF Virtual Rudder Feedback Core Pack combines a NAC-2 computer, Precision-9 nine-axis AHRS, NMEA 2000 starter kit, and dockside VRF setup. Its hydraulic-cylinder limit of 250 cc, 8A continuous output, 16A intermittent peak, 12V or 24V supply, IPX5 rating, 1.2 kg combined weight, and hydraulic or compatible steer-by-wire support provide clear system-selection details for a mid-size powerboat autopilot installation.

Setup and Network Considerations

Confirm the hydraulic cylinder volume or compatible steer-by-wire outboard system before selecting this core pack. Verify that the cylinder does not exceed 250 cc, then choose an appropriate steering drive and display. Plan the NAC-2 installation location, Precision-9 sensor location, NMEA 2000 starter-network connections, 12V or 24V supply, and electrical circuit capacity for the stated intermittent load before system commissioning.

Warranty and Support

Simrad warranty terms vary by product and region, and the supplied specifications do not provide a named warranty period for this core pack. Mulmarine.com can help you review hydraulic-cylinder volume, drive selection, VRF suitability, Precision-9 placement, NMEA 2000 requirements, power supply, and separate display or pump requirements before purchase. Review the applicable Simrad warranty coverage and documented package contents before ordering.

Before Ordering the Simrad NAC-2 VRF Virtual Rudder Feedback Core Pack

Confirm that your vessel uses hydraulic steering with a cylinder at or below 250 cc, or a compatible steer-by-wire outboard system. You should verify the required steering drive, display, Precision-9 sensor location, NAC-2 mounting space, NMEA 2000 network capacity, 12V or 24V power supply, 8A continuous and 16A peak drive needs, and whether VRF suits your steering configuration before purchase.
