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

Comfort ratio 19
CoastalBluewater

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

Capsize screening 2.07
LightHeavy

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

Displacement / length 163
EasygoingPowered-up

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

Sail area / displacement 18.4
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.
