, so a boat maybe quite a bit longer than its waterline length.
This measure is essential in determining a lot of properties of a vessel, such as how much water it displaces, where the bow and stern waves are,

Waterline — refers to an imaginary line marking the level at which ship or boat floats in the water. To an observer on the ship the water appears to rise or fall against the hull . Temperature also affects the level because warm water provides less buoyancy … Wikipedia
