Breadth is defined as the measurement from port inside edge to starboard inside edge. True or false?

• A. True
• B. False
• C. Only for frames
• D. Not defined at all

Answer: (A)

Breadth is the ship’s widest transverse dimension, the distance across the hull from one side to the other. In this context it is defined as the measurement from the inside edge of the port side to the inside edge of the starboard side at the ship’s widest point. This interior-to-interior measure standardizes the value by excluding shell plating thickness and any external fittings, giving a consistent figure for planning interior space and for calculations that depend on the hull’s width. Because this interior measurement is the common definition used in many training contexts, the statement is true. It’s not undefined, nor restricted to frames alone, since breadth is a defined crosswise dimension of the hull, often tied to the maximum usable width at the midship section.
