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

Comfort ratio 15
CoastalBluewater

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

Capsize screening 2.09
LightHeavy

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

Displacement / length 74
EasygoingPowered-up

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

Sail area / displacement 30.1
TenderStiff

56% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 56%

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

  • Lighter than ~93% of boats her size on file
  • Draws more than ~95% of boats her size on file
  • Narrower than ~84% of boats her size on file

Compared with 2723 boats of the same type within a quarter of her length.
