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

Comfort ratio 30
CoastalBluewater

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

Capsize screening 1.82
LightHeavy

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

Displacement / length 330
EasygoingPowered-up

14.6 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.6
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.
