Character

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

Shoal draughtDraws 1.09 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 26 — a moderate, middle-of-the-road motion.

Comfort ratio 26
CoastalBluewater

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

Capsize screening 1.79
LightHeavy

393 — very heavy for her waterline, a serious load-carrying cruiser.

Displacement / length 393
EasygoingPowered-up

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

Sail area / displacement 14.9
TenderStiff

42% of her weight is ballast — stiff, standing up well to her sails.

Ballast 42%

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