Is it easier to manuever a boat with twin engines with two rudders?
What would be the difference if it had one rudder? Or if you have a
single engine and two rudders?

In close quarters maneuvering it's nice to have the prop wash blasting
directly against the rudder, especially important with a single engine
boat but useful even with twins. The rudder deflects the prop wash
and creates a lateral (rotational) force.
