The high performance commercial autopilot CM880 is the result of over three years of working closely with workboat and freighter captains, ongoing software development and exhaustive sea trials in some of the world’s harshest marine environments.
The advanced, intelligent software built into the CM880 ensures enhanced course holding accuracy with minimal rudder movement.
Coursemaster also offers an optional CM528 analogue steering interface to suit 360-degree nozzle and jet drive steering systems. The CM880 accepts heading inputs from a fluxgate compass, flat top compass slave, or a digital input from a gyrocompass and naturally all
NMEA navigation sentences are supported. A range of optional remote steering positions and remote helms may also be fitted offering the helmsman more flexibility and freedom to carry out watch keeping and navigation.
The CM880 incorporates the performance and safety features required by the IMO and similar regulatory bodies. Its electronics have a high level of protection against supply fluctuations and electromagnetic interference.
