Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her moderate displacement on a narrow beam gives 27 — a moderate, middle-of-the-road motion.

Comfort ratio 27
CoastalBluewater

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

Capsize screening 1.90
LightHeavy

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

Displacement / length 249
EasygoingPowered-up

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

Sail area / displacement 18.0

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