Character

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

Shoal draftDraws 0.80 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 20 — a moderate, middle-of-the-road motion.

Comfort ratio 20
CoastalBluewater

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

Capsize screening 1.91
LightHeavy

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

Displacement / length 223
EasygoingPowered-up

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

Sail area / displacement 17.5
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.

  • Heavier than ~76% of boats her size on file
  • Draws less than ~75% of boats her size on file

Compared with 568 boats of the same type within a quarter of her length.
