Character

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

Shoal draftDraws 0.69 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 29 — a moderate, middle-of-the-road motion.

Comfort ratio 29
CoastalBluewater

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

Capsize screening 1.93
LightHeavy

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

Displacement / length 327
EasygoingPowered-up

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

Sail area / displacement 10.1
TenderStiff

50% of her weight is ballast — stiff, standing up well to her sails.

Ballast 50%

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