Character

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

LivelySea-kindly

Her light displacement on a moderate beam gives 19 — a quick, lively motion that feels every wave.

Comfort ratio 19
CoastalBluewater

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

Capsize screening 2.19
LightHeavy

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

Displacement / length 162
EasygoingPowered-up

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

Sail area / displacement 23.5

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

  • Draws more than ~92% of boats her size on file
  • Beamier than ~76% of boats her size on file

Compared with 2860 boats of the same type within a quarter of her length.
