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

Comfort ratio 23
CoastalBluewater

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

Capsize screening 1.91
LightHeavy

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

Displacement / length 289
EasygoingPowered-up

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

Sail area / displacement 14.5
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.
