Character

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

LivelySea-kindly

Her light displacement on a beamy beam gives 18 — a quick, lively motion that feels every wave.

Comfort ratio 18
CoastalBluewater

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

Capsize screening 2.14
LightHeavy

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

Displacement / length 170
EasygoingPowered-up

15.2 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 15.2
TenderStiff

42% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 42%

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