1.95 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.95

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

Displacement / length 271
EasygoingPowered-up

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

Sail area / displacement 15.0

A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.
