Already available and in use. Captain always has override ability.
And this is why, in real Navies' and other sea-going enterprises, there's always multiple people in the loop with regards to navigation and ship's movement, that way there will hopefully be someone with the brains and balls to go "umm, yeah, we're not doing that, jack-hole."
This reminds me of an event that happened on my ship back in 2004. We were landing helos, and the Air Boss kept calling the OOD and telling him he wanted "10 more minutes" to get another bird on the deck before we'd make another maneuver. The OOD who was at the time a Naval Academy butter-bar kept caving to the AB's demand. The Conning Officer, BM1 Obrien (he was going LDO) was a little less tolerant. As the ship was being forced to continue on a steady course to accommodate the air landings and takeoffs it eventually began to stray from it's assigned maneuvering box due (you know, that little thing designed to keep us from entering into shipping paths, or
hitting reefs) the Air Boss, predictably, called again saying he wanted "10 more minutes." The OOD hung up the phone and relayed this to BM1, and in a moment of awesome that I will cherish for the rest of my life, BM1 just looks at the OOD for a moment, then steps around her, flips a switch while announcing loudly "Red deck!" (the switch changed signal lights on the landing deck, his order halted all take offs and landings) and then immediately follows on with "Helm, come right to new course 120!" The Air Boss promptly called, raving at the OOD for the impertinence of changing course, but you know what? And this is also sort of the moral of this little anecdote. The Air Boss was in the wrong, and so was the OOD for going along with him. His actions were endangering the ship, but in this case, there was someone who wasn't willing to go along with the BS.
If that cruise liner had their version of BM1 Obrien handy this story wouldn't exist. Sure the Captain is a *expletive deleted*che bag, but he shouldn't be the only one getting hung out to dry. It takes more than one person to drive a ship. A Wasp-class requires no fewer than 6 people at various controls and watch stations in order to effectively move at all, let alone with any sense of order and purpose. Someone should have told this jack-hole no.
