What does "draft" refer to in boating terminology?

In boating terminology, "draft" refers to the depth of water required for a vessel to float. This measurement indicates how much of the vessel is submerged beneath the waterline when it is loaded. A vessel with a deeper draft requires more water to safely operate without running aground, while a vessel with a shallow draft can navigate in shallower waters. Understanding draft is essential for boaters to avoid grounding or hitting underwater obstacles, making it a critical concept in marine navigation and safety.

The other options describe different aspects of boating. The total weight a vessel can carry relates to its load capacity, while the speed at which a vessel travels pertains to its performance. The design shape of the vessel's hull refers to its structural attributes, which can affect stability and water resistance but do not define the draft itself.
