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

Comfort ratio 25
CoastalBluewater

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

Capsize screening 1.86
LightHeavy

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

Displacement / length 337
EasygoingPowered-up

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

Sail area / displacement 16.5
TenderStiff

52% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 52%

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