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

Comfort ratio 23
CoastalBluewater

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

Capsize screening 1.88
LightHeavy

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

Displacement / length 252
EasygoingPowered-up

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

Sail area / displacement 19.2
TenderStiff

46% of her weight is ballast — stiff, standing up well to her sails.

Ballast 46%

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