What does the term "draft" refer to in boating?

The term "draft" is defined as the vertical distance between the waterline and the bottom of the hull. This measurement is crucial for understanding how much water a boat needs to float safely and how deep it can go into the water without running aground. A boat's draft affects its stability, maneuverability, and the type of waterways where it can operate. For instance, a deeper draft implies the boat can operate in deeper waters but may be limited in shallow conditions.

When considering the other choices, the total weight a boat can carry pertains to its load capacity rather than its draft. The angle of the boat relative to the water surface is related to trim and stability, while the length of the boat specifically refers to its overall size but does not pertain directly to how much of the boat is submerged. Thus, defining draft correctly underlines the significant aspects of boat design and navigation, confirming the importance of choice B in understanding critical boating concepts.
