Ok. Now that we all understand and agree on the mechanics of steering a
motorcycle, let's consider this situation.

Twin screw inboard.
No wind.
Little or no current.

Helm hard over to port.
Starboard engine at idle
Starboard transmission in "forward".

Port engine at idle
Port transmission in "reverse".

Which way will the boat move?

Being that you are slightly right leaning and have lost a significant amount
of weight and your thrusters don't work, your boat will crab to port as long
as you don't sneeze while facing to port or fart while facing to stbd.

Depends on how long the boat is.

May not go anywhere considering engines are at idle


Oh, it will move.

I posed the question poorly. Better questions a

Which way will the bow move?
Which way will the stern move?

With the rudder in the neutral position the boat would pivot to port.

With the rudder hard port one may think the boat may tend to move even
more aggressively (bow) to port....


After seeing Jim's answer you have to understand that I *meant* to say "tend
to move even less aggressively to port".......and "walking" port to
starboard.......

Yeah, that's the ticket!

Downwards? Crashed in to the dock, received a holing?
