Better tell that to the Navy.
As told by an old friend of mine, who was in charge of the bow AA gun tubs on a heavy cruiser.
The captain checked and was told there were no Japanese ships anywhere near. They anchored to blow the tubes on one of their boilers. The other boilers were kept at full pressure just in case.
A Japanese cruiser hove into sight. Ray heard the captain on page, "Let go the bitter end!".
Ray yelled to his gun crews, "Grab as much ammunition as you can carry, and run aft as fast as you can go!"
The ship backed off the chain at full power. The whipping chain wiped the deck clean of anything forward of the winches.
Of course, the captain of a heavy cruiser would probably check the depth before dropping anchor.
That's the real "stupid" of that video.
