Character

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

LivelySea-kindly

Her light displacement on a moderate beam gives 22 — a moderate, middle-of-the-road motion.

Comfort ratio 22
CoastalBluewater

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

Capsize screening 2.00
LightHeavy

151 — light for her waterline, so she is easily driven and quick to accelerate.

Displacement / length 151
EasygoingPowered-up

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

Sail area / displacement 21.7
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

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