Offsets table

The offsets table, or table of offsets, is the numerical statement of a hull’s geometry: the half-breadths (and sometimes the heights of special lines such as the deck at side) tabulated at each station along the length and each waterline up the depth. Read together, the rows and columns reproduce the body plan, half-breadth plan, and sheer plan, so the table and the lines plan are two forms of the same information. Offsets are taken to a stated datum (centerline and baseline) in molded dimensions, and the table is what a loft, a plate cutter, or a hydrostatics program reads to compute displacement and the form coefficients. A faired table has every value on a smooth curve in each view.
