With the ship in a safe position in the harbour, the master and engineers reported that the defect had been rectified. The pilot instructed the master to thoroughly test the steering gear system before proceeding to the berth. When completed, the vessel was berthed safely.

The drink had clouded the judgement of the guest and the owner, but the captain knew that jet-skiing in the bay was prohibited. Even if the owner had sacked the captain on the spot, once they had sobered up, they would most likely have realised that the captain was speaking objectively, not subjectively.
