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

Capsize screening 2.00
LightHeavy

213 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 213
EasygoingPowered-up

16.3 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 16.3
TenderStiff

27% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.
