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 32 — a sea-kindly motion in a seaway.

Comfort ratio 32
CoastalBluewater

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

Capsize screening 1.78
LightHeavy

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

Displacement / length 267
EasygoingPowered-up

17.9 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 17.9
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.
