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

Comfort ratio 27
CoastalBluewater

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

Capsize screening 1.82
LightHeavy

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

Displacement / length 218
TenderStiff

37% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 37%

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