Rogue Wave. We hit one on a cruise. Were on 17th deck. Felt like an earthquake. Over in a few seconds.
These rogue waves, which appeared without warning, were described as nearly vertical walls of water, up to 100 feet high. These twelve story waves were often preceded by a trough so deep that sailors called it a "hole in the sea." The ship Raffaello hit this 20 meter rogue wave which did major damage.

Rogue waves are the most threatening and beautiful monsters of the ocean. Reaching heights of 100 feet or more, these mammoth waves are deadly, hard to predict, and more common than once thought. "I always tell people dinosaurs are dead, but big waves aren't," said Susan Casey, author of "The Wave." "To see a wave [that] is eighty or a hundred feet and be out in those waves, it's like being amongst the dinosaurs."
