Simrad AP70 MK2 IMO Pack (Solenoid) Technical Guide
The AP70 MK2 IMO Pack is a Type-Approved autopilot system that meets strict international maritime standards for commercial vessels. It includes the AC80S course computer, which is specifically designed to control heavy-duty solenoid steering systems found on tankers, tugs, and large workboats.
The AC80S course computer is engineered to drive solenoid valves rather than reversing pumps. This allows for the management of constant-running hydraulic power units, providing the high-reliability steering control required for continuous commercial operation in demanding sea states.
The RF45x is a medium-duty rudder feedback unit that provides extreme precision. On large commercial hulls, having physical, high-resolution feedback of the rudder position is critical to prevent over-steering and to ensure the vessel maintains its track during low-speed maneuvers.
Yes, the AP70 MK2 is designed for multi-bridge integration. You can connect multiple control heads and follow-up levers via the NMEA 2000 network, allowing the captain to maintain full autopilot control from the main bridge, wing bridges, or aft steering stations.
The AP70 MK2 features a bonded color display with wide viewing angles, ensuring the steering data is visible in all lighting conditions. The rugged rotary dial and dedicated buttons are designed for ease of use by crew members wearing gloves in rough weather.
