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 28 — a moderate, middle-of-the-road motion.

Comfort ratio 28
CoastalBluewater

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

Capsize screening 1.80
LightHeavy

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

Displacement / length 271
EasygoingPowered-up

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

Sail area / displacement 11.7

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