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 29 — a moderate, middle-of-the-road motion.

Comfort ratio 29
CoastalBluewater

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

Capsize screening 1.71
LightHeavy

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

Displacement / length 382
EasygoingPowered-up

14.3 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.3
TenderStiff

39% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 39%

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