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 38 — a sea-kindly motion in a seaway.

Comfort ratio 38
CoastalBluewater

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

Capsize screening 1.70
LightHeavy

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

Displacement / length 280
EasygoingPowered-up

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

Sail area / displacement 17.2
TenderStiff

41% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 41%

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