Character

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

Shoal draughtDraws 1.00 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her light displacement on a moderate beam gives 17 — a quick, lively motion that feels every wave.

Comfort ratio 17
CoastalBluewater

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

Capsize screening 2.15
LightHeavy

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

Displacement / length 178
EasygoingPowered-up

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

Sail area / displacement 25.7
TenderStiff

36% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 36%

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

  • Draws less than ~95% of boats her size on file

Compared with 2482 boats of the same type within a quarter of her length.
