So can a ship/boat actually turn 'too fast'? And what would the consequences be?
I know what happens to cars and bikes (I'm an amateur racer and a certified motorsport marshal), I can even imagine what happens to tracked vehicles but imagination fails me when 'floaters' are concerned.
For a few years now my town hosts one of the inshore European speedboat championship races*. Everytime I'm surprised to see those boats not slowing at all for a tight switchback around a buoy and still make the turn. I see it but I don't understand it. The only problem these guys seem to have is hitting the wake of a competitor and nosing down into the water. That stops them pretty damn fast.
* Here's a picture of one of the fastest classes, O-700 I think:
