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 26 — a moderate, middle-of-the-road motion.

Comfort ratio 26
CoastalBluewater

1.93 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.93
LightHeavy

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

Displacement / length 170
EasygoingPowered-up

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

Sail area / displacement 23.1
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

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