What a class is, and is not
Sister vessels share an underlying design and often a construction programme, but individual ships can still differ in length, tonnage, operator and delivered year. Class names can also be described differently by builders, operators and registers. This directory follows the class name recorded on each source-linked profile, so membership reflects the published data rather than an independent naval-architecture definition.
