Analyzed from the perspective presented in this essay, the design methods used to allow for frame-first construction do not equate with frame-first design. Quite the contrary, it is the quantification of longitudinal curves, versus transverse curves, that has an equal if not a dominant role in designing the overall hull shape. I believe that the idea of quantifying runs of planks at key points of curvature change on a hull formed the conceptual basis for the development of predetermination in Western ship design. As a result, when looking for evidence for the evolution of predetermination in ship design, it is as important to look for clues to the quantification of longitudinal curves in terms of planking patterns, design marks, longitudinal alignment of framing scarfs, etc., as it is to find clues of "active" framing elements that were erected prior to the planking.
