Character

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

Shoal draughtDraws 0.84 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 23 — a moderate, middle-of-the-road motion.

Comfort ratio 23
CoastalBluewater

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

Capsize screening 1.86
LightHeavy

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

Displacement / length 234
EasygoingPowered-up

14.1 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.1
TenderStiff

36% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 36%

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

  • Draws less than ~96% of boats her size on file
