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

Comfort ratio 15
CoastalBluewater

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

Capsize screening 2.25
LightHeavy

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

Displacement / length 168
EasygoingPowered-up

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

Sail area / displacement 16.2
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.
