Press reports from Sydney, NSW this week describe distressed residents hearing a ships whistle every 2 minutes which kept them awake one morning this week when Sydney was covered by a thick blanket of fog. Many misinterpreted it as a ship in distress.
Press reports from Wellington this week say that ferry schedules were disrupted by a southern right whale which took up residence near the ferry terminal. The manger of the shipping company said “the crew were operating the ship’s horn to warn off the whale”.
I wonder if the whale knows the collision regulations or can hear the “horn” when submerged.
