In marine engineering, what does the term "draft" refer to?

The term "draft" in marine engineering specifically refers to the vertical distance from the waterline down to the lowest part of the hull, which is typically the keel. This measurement is crucial for assessing the vessel's ability to navigate in various water depths and is instrumental in ensuring safe operation. A vessel's draft can influence its stability, load capacity, and maneuverability, making it an important factor for navigation and operational safety.

Understanding the draft is vital for avoiding grounding in shallow waters and ensuring that the vessel is operating within safe limits, especially in constrained or busy waterways. This term does not relate to weight distribution, fuel volume, or dock depth requirements, which are distinct concepts in the context of marine operations.
