Autopilot Core Pack

This pack includes the Simrad NAC-3 autopilot computer, RF25N rudder feedback unit, Precision-9 solid-state compass, plus all cabling and connectors required to build an NMEA 2000 network backbone or connect your autopilot system to an existing NMEA 2000 network. To create a complete Simrad Continuum autopilot system, just add a hydraulic pump or mechanical drive unit to suit your steering system, and choose a dedicated autopilot controller or Simrad multifunction display.

NAC-3 Autopilot Computer

The NAC-3 Autopilot Computer is recommended for boats above 10 metres (35 feet) in length. It is rated for high-current output of up to 30 amps continuous and 50 amps peak, plus a clutch output; this is suitable to operate high-current drive pumps including the Simrad RPU160 and RPU300, mechanical drives such as the Simrad DD15, hydraulic linear drives such as the HLD2000 series, and solenoid valves.

Multiple Control Options

Choose from a range of dedicated autopilot controllers, or control your autopilot from your existing multifunction display or glass bridge with full Simrad display integration. Install extra autopilot stations, ideal for dual-helm vessels, or add the Simrad WR10 wireless remote for instant steering and autopilot control from anywhere on board.

RF25N Rudder Feedback Unit

Rudder feedback units are sensors that connect to your rudder via a mechanical linkage and continuously report actual rudder position to your autopilot computer allowing the Simrad Continuum steering algorithm to make the best-informed steering decisions possible. These sensors are typically used on boats with inboard engines, on larger vessels, and in special applications where Virtual Rudder Feedback may not be suitable. The RF25N included in this pack connects directly to your boats NMEA 2000 network, simplifying the cabling required for installation.

Simrad Precision-9 Compass

The Precision-9 Compass supplies accurate heading and rate-of-turn information to your autopilot and other onboard systems over an NMEA 2000 connection. Heading is determined by an internal array of solid-state sensors that constantly measure motion and orientation on nine axes. The Precision-9s solid state technology is not only accurate and precise, but also exremely reliable with no internal moving parts. An easily adjustable mounting bracket and single-cable connection allow simple installation aboard any vessel, including up-mast mounting suitable for interference-free operation with steel hulls.

Automatic Tuning and Calibration

Auto-tuning simplifies setup and ensures optimal steering performance. Automatic compass calibration improves heading accuracy as you travel, using data gathered by the Simrad Precision-9s internal array of solid-state sensors.

Easy Installation

Industry-standard NMEA 2000 networking and NMEA 0183 input allow simple connectivity to sensors, autopilot controllers, and multifunction displays located anywhere on board.

Optically bonded 4.1-inch colour display

Visibility of heading, course and status information is essential when relying on your autopilot. The AP44 achieves this through a full-colour graphical display that allows for clear presentation of autopilot data and intuitive on-screen menus.

To ensure optimal visibility in all conditions, the AP44s LCD panel is optically bonded to its protective glass covering eliminating the possibility of condensation or fogging within the display. Transflective LCD technology makes use of reflected sunlight to brighten rather than obscure the screen, delivering superior day-time visibility and lower power consumption compared to traditional backlit displays.

Intuitive autopilot control

The point of a dedicated autopilot controller is to enable immediate access to auto-steering functionality, placing key controls within easy reach. Designed with that purpose in mind, the AP44 includes an intuitive interface with just four buttons and a push-to-enter rotary control dial. The rotary controller lets you make both large and small course adjustments with speed and precision, while also making it easy to select on-screen menu options without repeated button-presses.

Simrad Continuum steering technology

Every Simrad steering innovation builds upon a legacy encompassing over sixty years of autopilot development, which continues today at Simrad Yachtings autopilot research hub in Norway. This legacy is exemplified by the Continuum algorithm: the software that drives Simrad steering technology. Continuum brings all those years of research and on-water experience to your helm, for a smart pilot you can trust to take the wheel. Simrad autopilot solutions are available for a wide range of applications, from the smallest recreational boats up to large commercial vessels.

Automated turn patterns

Your Simrad autopilot can do much more than keep you on course. The AP44 gives you easy access to a range of built-in turn patterns designed to assist with fishing, diving, or just making a quick and efficient U-turn. Choose a turn, select port or starboard, and youre away. For more control, customise your turn pattern to execute complex spirals, zigzags, and other useful manoeuvres.

No Drift steering

No Drift mode integrates GPS navigation with auto-steering, using your position to counteract the effects of wind and tide. This lets you maintain a straight track over ground on your current heading, without having to manually set a waypoint or route. To unlock this powerful feature, simply combine the AP44 with an NMEA 2000 connected GPS receiver or compatible Simrad chartplotter.

Depth contour tracking

Network your AP44 autopilot system with a compatible echosounder module to enable depth contour tracking. In this mode, the AP44 will auto-steer to maintain a constant depth of water beneath your boat perfect for following depth contours while fishing or cruising, without having to define complex multi-waypoint routes.

Easy setup with auto tuning

Autopilot installation and commissioning doesnt have to be difficult or time consuming. The AP44 offers automatic tuning to ensure optimal auto-steering performance, with a simple on-screen commissioning process including dockside configuration and sea trial. Automatic compass calibration is available with the Simrad Precision-9 solid-state compass, further simplifying autopilot setup while ensuring heading accuracy.

Low-profile Glass Helm design

Designed to complement Simrad glass helm displays, instruments, and controllers, the AP44 features modern styling with a low surface-mount profile of just eight millimetres. A compact overall footprint enables mounting almost anywhere, while a large display ensures maximum visibility and ease of use.
