Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her light displacement on a beamy beam gives 15 — a quick, lively motion that feels every wave.

Comfort ratio 15
CoastalBluewater

At 2.40 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.40
LightHeavy

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

Displacement / length 158
EasygoingPowered-up

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

Sail area / displacement 26.0
TenderStiff

39% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 39%

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

  • Draws less than ~83% of boats her size on file
  • Beamier than ~85% of boats her size on file

Compared with 2608 boats of the same type within a quarter of her length.
