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

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

Displacement / length 291
EasygoingPowered-up

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

Sail area / displacement 15.4
TenderStiff

47% of her weight is ballast — stiff, standing up well to her sails.

Ballast 47%

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