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

Comfort ratio 19
CoastalBluewater

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

Capsize screening 2.01
LightHeavy

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

Displacement / length 127
EasygoingPowered-up

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

Sail area / displacement 20.9
TenderStiff

34% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 34%

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

  • Draws more than ~92% of boats her size on file
