Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her heavy displacement on a moderate beam gives 35 — a sea-kindly motion in a seaway.

Comfort ratio 35
CoastalBluewater

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

Capsize screening 1.71
LightHeavy

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

Displacement / length 413
EasygoingPowered-up

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

Sail area / displacement 15.4
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.
