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

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

Capsize screening 1.71
LightHeavy

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

Displacement / length 397
EasygoingPowered-up

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

Sail area / displacement 14.1
TenderStiff

42% of her weight is ballast — stiff, standing up well to her sails.

Ballast 42%

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