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

Comfort ratio 24
CoastalBluewater

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

Capsize screening 2.05
LightHeavy

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

Displacement / length 107
EasygoingPowered-up

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

Sail area / displacement 26.8
TenderStiff

53% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 53%

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