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 32 — a sea-kindly motion in a seaway.

Comfort ratio 32
CoastalBluewater

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

Capsize screening 1.75
LightHeavy

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

Displacement / length 336
EasygoingPowered-up

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

Sail area / displacement 16.5
TenderStiff

24% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 24%

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