Character

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

Shoal draftDraws 0.46 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 24 — a moderate, middle-of-the-road motion.

Comfort ratio 24
CoastalBluewater

1.84 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.84
LightHeavy

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

Displacement / length 172
EasygoingPowered-up

16.3 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 16.3
TenderStiff

30% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 30%

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

  • Heavier than ~78% of boats her size on file

Compared with 415 boats of the same type within a quarter of her length.
