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

Comfort ratio 15
CoastalBluewater

At 2.31 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.31
LightHeavy

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

Displacement / length 123
EasygoingPowered-up

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

Sail area / displacement 22.2
TenderStiff

44% of her weight is ballast — stiff, standing up well to her sails.

Ballast 44%

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