Rogue waves are sometimes mentioned synonymously with “gigantic waves.” A rogue wave might, or might not, be gigantic, and vice-versa. If a vessel is lying to the seas and a major wave approaches on the beam and rolls the ship hard, people would call that a rogue wave as it is traveling “rogue” to the direction of the normal seas. If it is twice as large or more, but approaches with the direction of the other seas, it’s just another wave, bigger perhaps, in the set. If a “gigantic wave”, approaches in the sets, and breaks over vessel wreaking all kinds of havoc, some might refer to that as a rogue wave as well, although it’s not really traveling “rogue” to the sets, etc. If the boat in this story was actually hit by a rouge traveling across the normal seas that were arriving down the Juan de Fuca, where did it come from? Perhaps it might have “bounced off” of some vertical rock face, etc.
