How to interpret it
Measurements can differ depending on which parts are included and the measurement method. A technical or contractual comparison requires knowing the exact reference for each figure.
Example
Hypothetical example: a vessel may have a different hull measurement from the length it occupies with a projecting component. The specification label indicates which measurement is being used.
Why it matters to you
It is a basic dimension for describing a vessel and understanding requirements or services that depend on its size; the applicable measurement method should always be checked.
Common points of confusion
It is not beam or draft. Two figures called boat length should not be treated as identical if they use different measurement definitions.
