Meaning and Definition
The vertical distance measured from the top of the keel to the underside of the deck plating at the side of a ship's hull, excluding the thickness of any deck sheathing.
In shipbuilding and naval architecture, 'molded depth' is a fundamental measurement of a vessel's internal depth. It is a design and structural dimension used to calculate tonnage, determine stability, and define the internal volume of the hull. It does not include external structures like the bulwarks or railings.
Dialectal Variation

Common Mistakes When Using “molded depth”
- Confusing it with 'draft' or 'draught' (the depth of the ship below the waterline).
- Confusing it with 'overall depth' (which includes the thickness of deck plating and other structures).
- Misspelling 'molded' as 'moulded' (AmE vs. BrE inconsistency).
FAQ
Frequently Asked Questions
No. Draft (or draught) is the vertical distance from the waterline to the bottom of the hull (keel). Molded depth is a fixed structural measurement from the keel to a specific deck, regardless of how much the ship is loaded.
It derives from naval architecture terminology. The 'molded' form or lines of a ship refer to the theoretical shape of its framework, represented on the 'molded lines' drawing. This depth is measured on that theoretical surface, not the exterior plated surface.
Almost certainly not. It is a highly specialized term used only in ship design, construction, regulation, and maritime commerce. It is not part of general English vocabulary.
Use 'molded' for American English and international technical documents (IMO, etc.). Use 'moulded' for British English publications and contexts. The meaning is identical.
The vertical distance measured from the top of the keel to the underside of the deck plating at the side of a ship's hull, excluding the thickness of any deck sheathing.

Learning
Memory Aids
Mnemonic
Think of a mold or cast for the ship's hull. The 'molded depth' is the *inside vertical measurement* of that basic structural mold, not the outside.
Conceptual Metaphor
The ship's hull as a molded object or container. The term frames the ship's structure as the product of a designed form, with 'depth' being a key dimension of that manufactured space.
