Character

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

LivelySea-kindly

Her heavy displacement on a moderate beam gives 26 — a moderate, middle-of-the-road motion.

Comfort ratio 26
CoastalBluewater

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

Capsize screening 1.84
LightHeavy

296 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 296
EasygoingPowered-up

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

Sail area / displacement 15.3
TenderStiff

39% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 39%

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