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 27 — a moderate, middle-of-the-road motion.

Comfort ratio 27
CoastalBluewater

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

Capsize screening 1.92
LightHeavy

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

Displacement / length 332
EasygoingPowered-up

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

Sail area / displacement 16.4
TenderStiff

40% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 40%

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