Twin screw boats still have prop walk, the difference is, you get to chose the engine and there for which way to walk your stern. You can split, which allows the boat to turn in place without advancing, you can do a reverse split that allows you to walk the boat straight sideways in either direction. You dont normally put both engines in gear in the same direction for close quarters maneuvering unless its windy, but you can. You can flare the bow like a boss with a cat and you can stop in a straight line by using both engines.
Twin screw cats really are amazing to park. The only thing better is a twin jet cat.
Any decent seamanship book will have a chapter on twin screw boat handling, Chapmans Im sure does.
