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

Capsize screening 1.66
LightHeavy

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

Displacement / length 343
EasygoingPowered-up

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

Sail area / displacement 15.7
TenderStiff

35% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 35%

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