Manawanui — what was running while the bridge was solving the wrong problem Times from the Court of Inquiry final report, paragraphs 19–20 and 61.

The two long bars are the point. The autopilot was engaged continuously from 18:13:08 until 18:27:40, and the diagnosis of thruster failure was held from 18:15:57 for eleven minutes and forty-three seconds. Both ran straight through the grounding.

Everything in the lower lanes happened inside those two bars: a rejected control demand, an alarm nobody remarked on, a speed reading that contradicted full astern, and a lookout's report that the thrusters were unobstructed. None of it reached the diagnosis.
