The Model Engineer and Amateur Electrician: 1915
The hull of a yacht is represented by three sets of lines, which are known as the cross-section or body plan, water line plan, and buttock line elevation. Any line that is a curve in one plan is always a straight line in the other two.
If the intersection of these lines coincide in all these drawings the shape of the hull must of necessity be fair in curvature, 7.¢., free from bumps, always, of course, providing the curves in the plans are not
unfair.
