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 31 — a sea-kindly motion in a seaway.

Comfort ratio 31
CoastalBluewater

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

Capsize screening 1.78
LightHeavy

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

Displacement / length 315
EasygoingPowered-up

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

Sail area / displacement 18.4
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.
