Platino’s crew relied completely on the autopilot to maintain a safe heading. Generally, no
crewmember was positioned to take immediate control if necessary, including at the time of the
accident'

Yeah Ping, that seems to be the case, the puzzle is that if the pilot was still active and the pilot rams were unable to be unloaded via the standby bypass valve,( hence the hard helm) why were no error messages recorded by the controller, not even the initial off course event. They certainly did a thorough investigation of the pilot hydraulics. The report was very unsettling, the thought of that boom, mainsheet bundle and traveller block destroying everything within reach makes me wonder how I would have dealt with this…not well I’m thinking!
With the
ferry grounding I think Kongsberg should carry the can, they supplied the autopilot and gave no instruction or warnings re the plotter/pilot interface, the crew assumed the pilot would resume
navigation from the ships
current position , not the waypoint astern or ahead.
