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

Comfort ratio 20
CoastalBluewater

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

Capsize screening 1.79
LightHeavy

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

Displacement / length 136
EasygoingPowered-up

27.2 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 27.2
TenderStiff

32% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 32%

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

  • Lighter than ~85% of boats her size on file
  • Narrower than ~95% of boats her size on file

Compared with 2957 boats of the same type within a quarter of her length.
