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 33 — a sea-kindly motion in a seaway.

Comfort ratio 33
CoastalBluewater

At 1.63 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.63
LightHeavy

386 — very heavy for her waterline, a serious load-carrying cruiser.

Displacement / length 386
EasygoingPowered-up

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

Sail area / displacement 18.0
TenderStiff

46% of her weight is ballast — stiff, standing up well to her sails.

Ballast 46%

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