Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her heavy displacement on a narrow beam gives 23 — a moderate, middle-of-the-road motion.

Comfort ratio 23
CoastalBluewater

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

Capsize screening 1.93
LightHeavy

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

Displacement / length 313
EasygoingPowered-up

18.1 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 18.1
TenderStiff

48% of her weight is ballast — stiff, standing up well to her sails.

Ballast 48%

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