How these are measuredCE · CLR · lead
Lead is the fore-and-aft distance from the hull’s lateral-resistance centre to the active sail plan’s effort centre.
CE · Centre of effort.
Area-weighted centre of the modeled active sail plan; not an aerodynamic pressure calculation.
CLR · Centre of lateral resistance.
Centroid of the immersed centreplane profile. Rudder and absent appendages are not included.

The rig desk is open. The rigger reads this whole repository — the Underhill knowledge, the India study, the engine — and can change it while you talk. Plate references and rig names in its answers become clickable.
