Scantling vs design draft

Scantling refers to the dimensions and structural details of the components of a vessel, such as the thickness of the hull plates and the sizes of the frames, ensuring the ship can withstand various stresses. The design draft, on the other hand, indicates the vertical distance between the waterline and the bottom of the hull (keel), which affects the vessel's buoyancy and stability. Essentially, scantling focuses on the structural integrity of the vessel, while design draft relates to its waterline and performance in water. Both are crucial for ensuring safety and efficiency in marine design.
