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

At 1.55 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.55
LightHeavy

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

Displacement / length 101
EasygoingPowered-up

13.6 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 13.6
TenderStiff

52% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 52%

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

  • Lighter than ~98% of boats her size on file
  • Draws less than ~93% of boats her size on file
  • Narrower than ~100% of boats her size on file

Compared with 2959 boats of the same type within a quarter of her length.
