Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her moderate displacement on a moderate beam gives 23 — a moderate, middle-of-the-road motion.

Comfort ratio 23
CoastalBluewater

2.03 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.03
LightHeavy

181 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 181
EasygoingPowered-up

20.8 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 20.8
TenderStiff

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

Ballast 47%

Light and lively — happiest day-sailing and coastal-hopping in settled weather.
