Character

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

LivelySea-kindly

Her moderate displacement on a moderate beam gives 24 — a moderate, middle-of-the-road motion.

Comfort ratio 24
CoastalBluewater

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

Capsize screening 1.96
LightHeavy

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

Displacement / length 259
EasygoingPowered-up

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

Sail area / displacement 17.0
TenderStiff

41% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 41%

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