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

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

Capsize screening 1.93
LightHeavy

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

Displacement / length 264
EasygoingPowered-up

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

Sail area / displacement 15.9
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

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