CoastalBluewater

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

Capsize screening 2.01
LightHeavy

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

Displacement / length 277
EasygoingPowered-up

18.4 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 18.4
