The word "keel" comes from Old English cēol, Old Norse kjóll, = "ship" or "keel".It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work De Excidio et Conquestu Britanniae, under the spelling cyulae (he was referring to the three ships that the Saxons first arrived in).

Keel: the main structural member of a traditional vessel, running fore and aft from bow to stern on its centerline. It provides ballast for stability, and resistance to leeway moving through the water. Keelson: an internal beam fixed to the top of the keel to strengthen the joint of the upper members of the boat to the keel.
Hogging is the stress a ship's hull or keel experiences that causes the center or the keel to bend upward. Sagging is the stress a ship's hull or keel is placed under when a wave is the same length as the ship and the ship is in the trough of two waves.
Draft (d) or (T) is the vertical distance from the bottom of the keel to the waterline. Freeboard (FB) is depth plus the height of the keel structure minus draft. Length at the waterline (LWL) is the length from the forwardmost point of the waterline measured in profile to the stern-most point of the waterline.
