Character

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

Shoal draftDraws 0.45 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 moderate beam gives 21 — a moderate, middle-of-the-road motion.

Comfort ratio 21
CoastalBluewater

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

Capsize screening 1.98
LightHeavy

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

Displacement / length 185
EasygoingPowered-up

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

Sail area / displacement 16.0
TenderStiff

33% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 33%

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

  • Heavier than ~81% of boats her size on file
  • Draws more than ~78% of boats her size on file
  • Beamier than ~76% of boats her size on file

Compared with 472 boats of the same type within a quarter of her length.
