Does this ship steerable props (such as the Azi-Pod)? If so,
then there's no way the helmsman could make the ship roll no
matter how hard he turned.

Are you telling me could not induce a roll on ship with pods?

I don't know if it's impossible to make the ship roll *any*
but it will certainly roll a heck of a lot less.


... Its a matter of sway, not propulsion.


No, it's a matter of forces around the centers of mass &
resistance. A rudder will make a ship roll because it is far
down below the waterline, and it only creates a force in one
direction. With an Azipod the ship is pulled (or pushed)
into a turn with much less heeling force generated. It's one
of the purposes of building it that way.

I suppose it follows that if the azipod (or any other
steerable prop) is used the exact opposite of how it should
be, the ship could roll even more... maybe that's what happened!

Anyway, google up the design brief on azipods if you think
I'm BSing.
