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 37 — a sea-kindly motion in a seaway.

Comfort ratio 37
CoastalBluewater

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

Capsize screening 1.70
LightHeavy

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

Displacement / length 401
EasygoingPowered-up

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

Sail area / displacement 12.4
TenderStiff

36% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 36%

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