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

Comfort ratio 10
CoastalBluewater

At 2.66 she sits above the 2.0 line — beamy for her weight, and happiest coastal.

Capsize screening 2.66
LightHeavy

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

Displacement / length 133
EasygoingPowered-up

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

Sail area / displacement 25.1
TenderStiff

44% of her weight is ballast — stiff, standing up well to her sails.

Ballast 44%

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

  • Lighter than ~84% of boats her size on file

Compared with 1387 boats of the same type within a quarter of her length.
