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

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

Capsize screening 1.94
LightHeavy

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

Displacement / length 280
EasygoingPowered-up

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

Sail area / displacement 17.9
TenderStiff

37% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 37%

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