Question 659 Rules of the Road

The correct answer is B) Length overall. The term "length" in the context of USCG Captain's License Examinations refers to the length overall (LOA) of the vessel. This is the maximum length of the vessel, including all fixed projections, from the foremost part of the stem to the aftermost part of the stern. This is the standard measurement used for vessels and is the most relevant for determining the appropriate licensing requirements. The other options are not correct because they refer to different length measurements that are not the primary consideration for Captain's License Examinations. Registered length, waterline length, and length between perpendiculars are less common or specific measurements that do not necessarily align with the general understanding of a vessel's overall size and dimensions.
