There is actually an international commission planning to introduce "WTC", water traffic control, so that no dumb cruiser captain can be able to select personal routes for his cruise liner. This actual guy went way off his ideal route, allegedly to "show off" and pass the idyllic island very close. Imagine that in our trade...
From what the owners said in their press conference today that was all in place on that ship - pre-programmed route with an 'alarm' system for deviation.
Thanks for the options given to a F/O with a crazy or incapacitated captain! Are there more to come?
Please use your imagination - can you not answer this yourself? You talk, after all, of "Imagine that in our trade...". At age 61 I would have thought you had considered this problem at some stage?
