A problem which was rarely, if ever, encountered in the days of sail, but which is very much a problem with today's much larger ships and particularly oil tankers, is "hogging" and "sagging". Hogging is where the ship is "crested" on a large wave with little or no water supporting the ends of the ship. Sagging is when the ship is supported by two waves, one at either end of the ship, allowing it to sag between them. It's the reason why half the oil tankers which sink go down. They twist and distort as they hog and sag and eventually the ship's back is broken. Hello, Davy Jones! (no, NOT the little git in the Monkees!)
