That's not correct - according to the Collision Regulations, simply being a large ship does not make you "restricted in ability to maneuver." That definition is reserved for vessels carrying out an activity which restricts them from altering their course, such as dredging or mine clearing. A large oil tanker may be "constrained by draught" in a narrow channel in which case it does indeed have right of way over smaller vessels, but larger vessels will be constrained too so "priority over everything" becomes a pretty meaningless concept as everyone will have it.
In open water, large vessels like that give way to smaller vessels when appropriate all the time.

Nonetheless, I'd expect a far more agile battleship to be able to move itself out of harm's way.
