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 37 — a sea-kindly motion in a seaway.

Comfort ratio 37
CoastalBluewater

At 1.65 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.65
LightHeavy

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

Displacement / length 329
EasygoingPowered-up

14.3 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.3
TenderStiff

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

Ballast 37%

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