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

Comfort ratio 29
CoastalBluewater

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

Capsize screening 1.80
LightHeavy

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

Displacement / length 424
EasygoingPowered-up

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

Sail area / displacement 14.1
TenderStiff

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

Ballast 39%

A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.
