Well, the USS Missouri weghts 41.000 tons, which probably means around 50-55.000 tons full. That should explain the sheer impossibility of
a- bringing it to an almost full stop with a simple anchor in a matter of seconds. The most reasonable outcome would just be that the anchor would snap like a thread.
b- turning it sideways using the anchor as a pin. Even if the chain didn't break, the anchor would just drag along the ocean floor. And even if (somehow) it did manage to stop the ship, the bow of a vessel like that is not intended for that type of sideway force and would likely break off.
Really, 50.000+ tons weight an awful lot :)
