Character

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

LivelySea-kindly

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

Comfort ratio 23
CoastalBluewater

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

Capsize screening 1.97
LightHeavy

273 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 273
TenderStiff

45% of her weight is ballast — stiff, standing up well to her sails.

Ballast 45%

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