After sailing on large ships for a few years, I've seen and heard the Conning officers give the wrong helm
order a few times. And this is a good example of what can and could happen.
That is why certain bridge officers are suppost to be alert to possible navigation
errors and correct them. But they have to be alert also... A minor detail there. Usually the Pilot has the conn and the since the Captain
is held responsible, he is overseeing the Pilot, and the Navigation
officer, 2nd Mate, keeps the Captain informed of where the ship is in the channel. That is the usual command chain on the bridge of a ship. But gremlins do stick their fingers in there and cause a confusion factor that is hazardous to the ship and the deck
