I've never heard the story of the Curacoa, but the summary on Wikipedia is bonkers: https://en.wikipedia.org/wiki/HMS_Curacoa_(D41)#Collision https://en.wikipedia.org/wiki/HMS_Curacoa_(D41)#Collision Queen Mary is zigzagging around because maybe it'll confuse U-boats if there are any. Curacoa is trying to just go in a predictable straight line to maximize ability to defend against enemy aircraft if there are any. Queen Mary turns and slices straight through the Curacoa, doesn't stop to help because maybe there might be U-boats, and then everybody spends years in litigation after the war about whose fault it was.
