Two columns. Triangle areas from the rig measures. SA/D only when displacement is light or half load. Loaded displacement does not produce SA/D.

Foretriangle: 24.0 m²

This column has no usable figure yet.

Cloth triangles, not the sail that is hoisted.

How the figure is built

Foretriangle = (I × J) / 2. Mainsail triangle = (P × E) / 2. Genoa = (I × LP) / 2. SA/D follows the FairHelm formula page: square feet divided by (pounds / 64) to the power 2/3. 1 m = 3.280839895 ft, 1 kg = 2.2046226218 lb.
