Like I wrote, the Captain and pilot's orders must be followed once given.with no gps/radar screens, charts, binoculars, common language, visibility, view, local knowledge, you suppose that, the helmsman, not following an officers orders is the way to go. really?
However, coming into that turn is extremely conspicuous even without charts or other aids. You follow a line of buoys and then another line of buoys goes off to the right. The point of CRM is to recognize that others are resources and allow them to point out potential issues before those become operational problems.
