Every system in your engine room carries a manual, a log and a named control. AI came aboard without any of the three.
The guests fly out and your season starts: everything that broke over six weeks of charter is now yours, plus the survey file, plus the handover you owe your rotation. Somewhere in the middle of that, your second is troubleshooting the aft genset with a chatbot, because pasting the fault code in is faster than finding the manual. Fair enough. Except the answer might be wrong in a way that costs a bearing, the fault history he pasted describes this vessel and where it's been, and nothing on the noticeboard says which tools are approved, what never goes into them, or who checks machine-drafted text before it goes into the PMS or a warranty claim. Every other system aboard was commissioned before the department trusted it. AI can run the same way: tools listed, limits written, a review step in the routine. It starts with knowing your position.
