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

Comfort ratio 12
CoastalBluewater

At 2.45 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.45
LightHeavy

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

Displacement / length 123

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