Character

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

Shoal draftDraws 1.07 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her moderate displacement on a narrow beam gives 38 — a sea-kindly motion in a seaway.

Comfort ratio 38
CoastalBluewater

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

Capsize screening 1.76
LightHeavy

181 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 181
EasygoingPowered-up

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

Sail area / displacement 17.3
TenderStiff

31% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 31%

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

  • Heavier than ~88% of boats her size on file
  • Beamier than ~91% of boats her size on file

Compared with 121 boats of the same type within a quarter of her length.
