2.11 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.11
LightHeavy

288 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 288
TenderStiff

45% of her weight is ballast — stiff, standing up well to her sails.

Ballast 45%

A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.
