hogging
1. A condition in which the hull of a vessel bends upward so the ends of the keel are lower than the middle. (Contrast with sagging.) Hogging can occur when the peak of a wave is amidships or during loading or unloading of a vessel and can damage her or even break her in half.
2. A permanent distortion of the hull in the same manner caused, over time, by the bow and stern of a ship being less buoyant than the midships section. During the Age of Sail, shipwrights employed a number of different designs of braces to stiffen ships' hulls against this warping.
sagging
A condition in which the hull of a vessel deflects downward so the ends of the keel are higher than the middle. The opposite of hogging. Sagging can occur when the trough of a wave is amidships or during loading or unloading of a vessel and can damage her or even break her in half.
It is believed that a combination of hogging and sagging along with one brief bottom touch is what doomed the Edmond Fitzgerald.
