What do the terms breadth, molded depth, freeboard, and draft mean in the context of ship design?
Understand the Problem
The question is referencing a diagram that illustrates various measurements related to ship size. It identifies different components such as breadth, molded depth, freeboard, and draft. The purpose is likely to understand the terminology and dimensions that are critical in ship design and construction.
Answer
Breadth: maximum width; Molded Depth: keel to freeboard deck beam; Freeboard: waterline to upper deck; Draft: waterline to keel.
In ship design, 'breadth' is the maximum width of the ship, 'molded depth' is the distance from the top of the keel to the top of the freeboard deck beam, 'freeboard' is the vertical distance from the waterline to the upper deck edge, and 'draft' is the depth of the ship's hull from the waterline to the keel.

In ship design, 'breadth' is the maximum width of the ship, 'molded depth' is the distance from the top of the keel to the top of the freeboard deck beam, 'freeboard' is the vertical distance from the waterline to the upper deck edge, and 'draft' is the depth of the ship's hull from the waterline to the keel.
More Information
These measurements are critical for the design, safety, and performance of a vessel.
Tips
Common mistakes include confusing molded depth with overall depth, and misunderstanding freeboard as the entire height of the ship.
