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

Comfort ratio 13
CoastalBluewater

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

Capsize screening 2.17
LightHeavy

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

Displacement / length 88
EasygoingPowered-up

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

Sail area / displacement 24.5
TenderStiff

45% of her weight is ballast — stiff, standing up well to her sails.

Ballast 45%

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

  • Lighter than ~84% of boats her size on file
  • Narrower than ~77% of boats her size on file

Compared with 2466 boats of the same type within a quarter of her length.
