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 40 — a heavy, notably soft motion offshore.

Comfort ratio 40
CoastalBluewater

At 1.61 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.61
LightHeavy

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

Displacement / length 311
EasygoingPowered-up

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

Sail area / displacement 15.0
TenderStiff

40% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 40%

Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.
