What does "draft" refer to in the context of a vessel’s operation?

In the context of a vessel’s operation, "draft" refers specifically to the minimum water depth required for safe navigation. It indicates how deep the hull of a boat or ship sits in the water and is measured from the waterline to the lowest point of the hull. Knowing the draft is crucial for ensuring that the vessel can safely traverse various waterways without risking grounding or damage.

For instance, if a vessel has a draft of 5 feet, it needs to navigate in waters that are deeper than this to avoid running aground. This measurement influences route planning and can determine which channels or docks are accessible for a particular vessel, especially in shallow areas. Understanding draft is essential for marine technicians as it impacts overall vessel performance and safety during operation.
