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 16 — a quick, lively motion that feels every wave.

Comfort ratio 16
CoastalBluewater

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

Capsize screening 2.10
LightHeavy

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

Displacement / length 132
EasygoingPowered-up

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

Sail area / displacement 24.1
TenderStiff

46% of her weight is ballast — stiff, standing up well to her sails.

Ballast 46%

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