I know of a ferry that a local warf built that had two bridges, and a combined throttle and rudder in each.
The thing is that when moving from one bridge to the other, the crew had to flip a switch to indicate what direction was forward. And quite often they forgot.
End result was a long history of damaged because ferry would ram the pier when the crew was actually attempting to move away from it.
