Hello; You would think they could come up with some kind of radar or distancing photography and let it go through a computer to find out the distance between swells and the height of them and find out which are damage to the ship compared to the ship's size so that the whole doesn't go through major stressed because of the distance and height of the swells so the captain would know what speed to travel at or to take on water heaters ballast to be deeper in the water or shallow water in the water to lessen the chance of a stress fracture in the steel. These were pretty intense! It doesn't matter how big a ship looks at dock, when it gets to the middle of the ocean it's just as tiny & insignificant of a speck as anything else out there! That one scene though made my stomach drop! The one where the guys in the sailboat were thrown at the dock by the wave. I thought one guy was gonna smack right into the decking!
