Detailed description

The NAC-2 Autopilot Computer is the central component of your Navico autopilot system, designed for boats up to 10 meters (35 feet). It processes heading and rudder feedback sensor data to accurately steer your vessel, in conjunction with a control head and a drive unit (pump or mechanical ram).

Performance and Power

The NAC-2 is capable of delivering a continuous output current of 8A with peaks up to 12A, making it compatible with a wide range of 12/24V DC drive units, including medium-sized hydraulic pumps and mechanical drives. Its maximum power consumption is 750W, but in typical use, it depends directly on the demand from the rudder actuator. The enclosure is IPX5 certified, ensuring protection against water jets and secure installation in protected marine environments.

Connectivity and System Integration

Designed for seamless integration, the NAC-2 features an NMEA 2000 (Micro-C) port for easy connection to multifunction displays, compasses, and other sensors within the B&G, Simrad, or Lowrance ecosystems. It also includes an NMEA 0183 (IN/OUT) port to ensure compatibility with older equipment. The computer supports variable voltage/resistive (0-5V) rudder feedback sensors and has an external alarm output (max 100 mA).

Positioning in the Navico Range

The NAC-2 is the mid-range model in the Navico computer lineup. It sits above the NAC-1, intended for smaller cable-steered systems, and below the NAC-3, which is designed for larger boats requiring higher output current for high-capacity drive units. The NAC-2 is therefore an ideal choice for the majority of powerboats and sailboats under 35 feet.

Expert opinion

Pol CONIN

Digital Manager

« NAC-2: The benchmark for units up to 10 meters »

The NAC-2 is the autopilot computer we recommend for the vast majority of installations on units under 10-12 meters. It represents the right balance between output power and compactness. Its 8A continuous (12A peak) capacity is perfectly sized for the most common hydraulic pumps and mechanical cylinders in this boat segment. This computer is the brain of the system; its reliability is therefore paramount. Compliant with EN60945 standard for shock and vibration and with its IPX5 protection rating, it is designed to last in a marine environment. Its dual NMEA 2000 and NMEA 0183 connectivity makes it a versatile choice, both for a new installation and for upgrading an existing system.

Frequently Asked Questions

Need help? Contact us

For what type and size of boat is the NAC-2 computer recommended?

The NAC-2 autopilot computer is designed for boats up to 10 meters (35 feet) in length. It is ideal for the majority of recreational boats equipped with medium-sized hydraulic or mechanical steering systems.

Is the NAC-2 computer waterproof?

Yes, the NAC-2 computer has an IPX5 rating. This means it is protected against water jets from all directions, allowing for secure installation in protected marine environments.

What is the difference between the NAC-2 and other Navico computers like the NAC-1 or NAC-3?

The NAC-2 is the mid-range model in the Navico lineup. It sits above the NAC-1 (intended for small cable-steer systems) and below the NAC-3, which is designed for larger boats requiring higher output current for high-capacity drive units.

Can the NAC-2 be connected to a NMEA 2000 network?

Yes, the NAC-2 is equipped with a NMEA 2000 (Micro-C) port for easy integration with multifunction displays, compasses, and other compatible sensors.

Can I connect older equipment using NMEA 0183?

Yes, the NAC-2 has an NMEA 0183 (input/output) port to ensure compatibility with older equipment. It supports baud rates of 4.8, 9.6, 19.2, and 38.4 kbaud.

What type of rudder feedback sensor is compatible with the NAC-2?

The NAC-2 is compatible with variable voltage or resistive rudder feedback sensors, which provide a 0-5V signal.

Is the NAC-2 compatible with Simrad, B&G, and Lowrance multifunction displays?

Yes, the NAC-2 is designed for seamless integration within Simrad, B&G, and Lowrance ecosystems via the NMEA 2000 network.

What is the NAC-2's load on the NMEA 2000 network (LEN)?

The NAC-2 computer represents a load of 1 LEN (Load Equivalency Number) on the NMEA 2000 network.

Is there a safety distance to maintain from the magnetic compass?

Yes, during installation, you must maintain a safety distance of at least 500 mm (20 inches) between the NAC-2 computer and any magnetic compass to avoid interference.

Where can I install the NAC-2 computer on board?

Thanks to its IPX5 rating, the NAC-2 can be installed in locations protected from the weather but which may be subject to water spray, such as a locker or console. However, it must not be submerged.

Is it possible to connect an external alarm sounder to the NAC-2?

Yes, the NAC-2 has an external alarm output. You can connect a buzzer or a relay (maximum current of 100 mA) to be alerted to autopilot alarms.

Is the NAC-2 difficult to configure?

The NAC-2 is configured via a compatible multifunction display (Simrad, B&G, Lowrance). It involves two main steps: dockside setup (boat type, autopilot type) and sea tuning to refine performance.

Can the NAC-2 be used for wind-based navigation modes?

Yes, when connected to a wind sensor via the NMEA 2000 network, the NAC-2 supports wind-based navigation modes. It can follow an apparent wind angle (AWA) or a true wind angle (TWA) depending on the conditions.
