Character

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

LivelySea-kindly

Her light displacement on a narrow beam gives 25 — a moderate, middle-of-the-road motion.

Comfort ratio 25
CoastalBluewater

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

Capsize screening 1.93
LightHeavy

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

Displacement / length 153
EasygoingPowered-up

22.8 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 22.8
TenderStiff

39% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 39%

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