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

Comfort ratio 28
CoastalBluewater

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

Capsize screening 1.83
LightHeavy

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

Displacement / length 338
EasygoingPowered-up

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

Sail area / displacement 15.9
TenderStiff

50% of her weight is ballast — stiff, standing up well to her sails.

Ballast 50%

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