The Situation

You're the Chief Officer on watch, in ballast, transiting past Mauritius on route to Brazil. It's late evening. The Master, who's been at a crew birthday party, arrives on the bridge and suggests altering course closer to the coast — mobile signal has been poor for days, and everyone wants to make calls home.

The Lesson

An unjustified course alteration toward a hazard doesn't become sound seamanship because the Master approved it — and the OOW/Chief Officer on watch is the last real check before it becomes irreversible.

Human Element

Every individual choice in the real event looked small in isolation — one course alteration, one skipped lookout, one drink too many. None of them alone caused the grounding. Together, and unchallenged, they did.

Try the First Decision

The Master wants to alter course closer to shore for phone signal — no navigational or operational justification, just convenience. As the officer on watch, what do you do?

A. Raise the safety concern directly — the course change brings the ship needlessly close to charted hazards
B. Comply with the Master's instruction and alter course closer to shore
