Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her light displacement on a narrow beam gives 37 — a sea-kindly motion in a seaway.

Comfort ratio 37
CoastalBluewater

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

Capsize screening 1.76
LightHeavy

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

Displacement / length 176
EasygoingPowered-up

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

Sail area / displacement 19.3
TenderStiff

26% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 26%

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

  • Draws more than ~75% of boats her size on file
