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 41 — a heavy, notably soft motion offshore.

Comfort ratio 41
CoastalBluewater

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

Capsize screening 1.70
LightHeavy

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

Displacement / length 323
EasygoingPowered-up

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

Sail area / displacement 16.1
TenderStiff

51% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 51%

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