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

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

Capsize screening 2.02
LightHeavy

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

Displacement / length 127
EasygoingPowered-up

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

Sail area / displacement 18.7
TenderStiff

24% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 24%

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

  • Beamier than ~89% of boats her size on file

Compared with 1473 boats of the same type within a quarter of her length.
