Character

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

LivelySea-kindly

Her moderate displacement on a moderate beam gives 25 — a moderate, middle-of-the-road motion.

Comfort ratio 25
CoastalBluewater

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

Capsize screening 2.03
LightHeavy

186 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 186
EasygoingPowered-up

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

Sail area / displacement 20.0
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 ~80% of boats her size on file
  • Beamier than ~81% of boats her size on file

Compared with 2709 boats of the same type within a quarter of her length.
