Character

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

LivelySea-kindly

Her moderate displacement on a moderate beam gives 21 — a moderate, middle-of-the-road motion.

Comfort ratio 21
CoastalBluewater

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

Capsize screening 1.98
LightHeavy

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

Displacement / length 217
EasygoingPowered-up

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

Sail area / displacement 14.1
TenderStiff

29% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 29%

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