Description
Virtual Rudder Feedback and Algorithm Analysis
Physical rudder feedback sensors often fail due to mechanical wear or corrosion in harsh bilge environments. The Simrad AP44 VRF Medium Capacity Pack utilizes Virtual Rudder Feedback algorithms to eliminate these sensors. This system maintains precise heading without mechanical linkage.
Network integration utilizes the NMEA 2000 protocol for high-speed communication between the AP44 controller and NAC-2 computer. The system supports various hydraulic and mechanical drive units across the Simrad ecosystem. Waterproof construction ensures the display meets IPX7 environmental standards.
Strategic Vessel Application
Essential for outboard and sterndrive boats up to 35 feet requiring a sensorless autopilot solution.
Technical Key Features
- VRF technology eliminates physical rudder feedback sensors
- NMEA 2000 certified for universal system telemetry
- NAC 2 computer supports medium current drives
- IPX7 rated display features 4.1 inch screen
- Automated tuning optimizes vessel steering response curves
- Rotary dial allows precise 1 degree adjustments
- Low profile design facilitates flush mount installation

Simrad AP44 VRF Medium Capacity Pack Technical Guide
This comprehensive pack includes the AP44 color controller, a NAC-2 autopilot computer, the Precision-9 solid-state compass, and a reversing hydraulic pump. It is designed for outboard and inboard vessels up to 35 feet. The "VRF" designation means it supports Virtual Rudder Feedback, simplifying installation by removing the need for a mechanical sensor.
Simrad's VRF technology uses advanced algorithms to estimate rudder position based on the vessel's turn rate and pump activity. This is highly effective for outboard-powered boats where mounting a physical sensor is difficult. VRF reduces mechanical failure points and streamlines the commissioning process via the AP44 setup wizard.
The Precision-9 provides accurate heading, rate-of-turn, roll, and pitch data over the NMEA 2000 network. This 9-axis sensing allows the AP44 to make precise steering corrections even in heavy following seas. It supports automatic calibration, making it one of the most reliable compasses for mid-sized autopilot systems.
Yes, the AP44 includes built-in turn patterns such as U-turns, Spiral turns, and Depth Contour Tracking (when integrated with a compatible sonar). These features are invaluable for anglers and long-distance cruisers. The intuitive rotary dial on the AP44 allows for quick 1-degree or 10-degree course adjustments.
The NAC-2 computer in this pack is rated for pumps with a continuous current draw of up to 8 Amps (16 Amps peak). This typically supports hydraulic cylinders up to 14 cubic inches. If your boat has larger steering rams, you would need the NAC-3 computer and a high-capacity pump kit. Check your cylinder displacement before installation.
