Fairing

Fairing is the process of adjusting a hull’s defining lines until every curve is smooth and the three orthogonal views agree at every point: a waterline, a buttock, and a station that all pass through the same point in space must show that point consistently in the half-breadth, sheer, and body plans. Traditionally done full-size on the mold loft floor, fairing is now done in a surface-modeling CAD system that enforces continuity of curvature, not just position, so the surface carries no flats or unfair bumps that would show on the finished plating or disturb the flow. A faired surface is the precondition for an accurate offsets table, plate development, and clean hydrodynamics.
