LivelySea-kindly

Her moderate displacement on a moderate beam gives 28 — a moderate, middle-of-the-road motion.

Comfort ratio 28
CoastalBluewater

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

Capsize screening 1.88
LightHeavy

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

Displacement / length 185
EasygoingPowered-up

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

Sail area / displacement 7.8
TenderStiff

45% of her weight is ballast — stiff, standing up well to her sails.

Ballast 45%

Light and lively — happiest day-sailing and coastal-hopping in settled weather.
