Hey Dan,
Apparently, the SPOT data indicates that the “OK” button – which can only be triggered manually - was pushed at 1825, at 1841 and then at 1949. A very slight change of heading was made after the last “entry” … And then, NOTHING - no further "OKs" for the next several hours until the time of impact…
It was also mentioned elsewhere that a new engine had recently been installed on AEGEAN, which raises the possibility of an improper/faulty installation of the exhaust system, which could have produced CO poisoning… Certainly the conditions – light following breeze, exhaust wafting back into the cockpit – might have produced a similar result, no?
SG has found some interesting pics of the boat… The nav station appears to show no installed navigational gear or instrumentation whatsoever, so it seems unlikely much in the way of paper chart work was the routine aboard AEGEAN… The plotter at the helm was likely where all the navigation took place, and if that unit happened to go TU, well…. who knows?
One thing this tragedy a sobering reminder of, IMHO this sort of thing is FAR more likely to happen under power, than under sail…
Best regards,
Jon
