What does the term "draft" refer to in nautical terminology?

The term "draft" in nautical terminology specifically refers to the distance a ship's hull extends below the waterline. This measurement is crucial because it dictates how deep the vessel sits in the water, which has direct implications for stability, sea conditions, and clearance under bridges or piers.

Understanding draft is essential for safe navigation, as it helps determine whether a vessel can operate in certain depths of water. A ship with a significant draft requires deeper waters to avoid running aground, making it critical for the captain and crew to be aware of the draft when planning routes and operations. The draft can change based on factors such as cargo load and fuel levels, making it a vital measurement in maritime operations.
