In maritime rules, what is the word "length" referring to?

The term "length" in maritime rules typically refers to "length overall." This is a crucial measurement as it indicates the maximum overall length of a vessel from the tip of the bow to the end of the stern. This measurement is significant for various regulatory purposes, including determining dock space, calculating tonnage, and ensuring compliance with maritime rules that may impose size restrictions.

Understanding this definition is essential for operators as it impacts navigation, safety regulations, and the vessel's registration process. While other interpretations of length like length between perpendiculars and waterline length may have specific applications, they do not represent the general standard used in maritime context. The length overall provides a comprehensive understanding of the vessel's dimensions as it pertains to all operational aspects on the water.
