Character

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

LivelySea-kindly

Her moderate displacement on a narrow beam gives 24 — a moderate, middle-of-the-road motion.

Comfort ratio 24
CoastalBluewater

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

Capsize screening 1.91
LightHeavy

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

Displacement / length 220
EasygoingPowered-up

19.2 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 19.2
TenderStiff

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

Ballast 45%

Powered-up and quick to accelerate — this one likes to sail.
