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

Comfort ratio 25
CoastalBluewater

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

Capsize screening 2.07
LightHeavy

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

Displacement / length 147
EasygoingPowered-up

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

Sail area / displacement 17.6
TenderStiff

29% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 29%

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