Here in Halifax harbour, if I go parallel to and within a couple hundred feet of the Panamax floating dry dock, a big chunk of steel, with the auto helm on, I'll get steered right off course and into the side of the dry dock. Same with big ships at anchor.
Some years ago, A guy with a Nonsuch 36 under auto helm T-boned a container ship in the harbour while he was below and not watching. The steel hull got him.
