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

Comfort ratio 17
CoastalBluewater

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

Capsize screening 2.13
LightHeavy

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

Displacement / length 146
EasygoingPowered-up

19.3 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 19.3
TenderStiff

31% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 31%

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