How long does it take to switch to alternate system once the decision has been made?
Hydraulic back up, almost instantly. Rigging the winches and going completely manual, perhaps 10-15 min. A destroyer can also get some steering by going full ahead with one screw, and reverse with the other. It can also stop very quickly.
