Character

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

Shoal draftDraws 0.81 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her heavy displacement on a moderate beam gives 24 — a moderate, middle-of-the-road motion.

Comfort ratio 24
CoastalBluewater

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

Capsize screening 1.83
LightHeavy

280 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 280
EasygoingPowered-up

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

Sail area / displacement 16.6
TenderStiff

41% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 41%

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

  • Heavier than ~85% of boats her size on file
  • Draws more than ~94% of boats her size on file

Compared with 590 boats of the same type within a quarter of her length.
