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

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

Capsize screening 1.78
LightHeavy

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

Displacement / length 303
EasygoingPowered-up

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

Sail area / displacement 9.6
TenderStiff

38% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 38%

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