Simrad NAC-2 VRF Virtual Rudder Feedback Core Pack

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.

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.

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.
