The Sodak class has skegs on the outer shafts and I was wondering if that class could also do the "Barn Door Stop" maybe if they turned the rudders in the opposite direction than an Iowa facing out instead of in?
A full crash back is almost a non-event. That's where all four screws are reversed from full ahead to full astern. It takes a little over a mile for the ship to come to a stop before going in reverse, but there is no feeling of inertia throwing you forward - unless you turn the rudders inboard toward each other to close off the passage of water between the twin keels. That is called a "Barn Door Stop" and only the Wisconsin has ever tested it. A former XO of Whisky said that when they threw a piece of wood over the side from the bow at the onset of that maneuver, the ship came to a stop with that wood no further aft than turret III. That's stopping a 57,000 ton ship traveling at 33 knots in about 600 feet, which means that anything that is not tied down winds up on deck or against a forward bulkhead.
