FIGURE 46 a&b.

Double curvature of plank and ribband runs as documented on a historic model and draft. In Figure 46a wale runs are accentuated in black on a photograph (after Winter 1956:Plate X) of a contemporary fifteenth-century votive model from Mataro in Catalonia, Spain; it is now exhibited in the Prince Hendrik Maritime Museum in Rotterdam. In Figure 46b longitudinal runs are accentuated in black on a body plan detail from a 1685 draft by François Coulomb (Musée de la Marine 1685:PH 90252). (Modified by T. Pevny)
