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

Comfort ratio 25
CoastalBluewater

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

Capsize screening 1.99
LightHeavy

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

Displacement / length 215
EasygoingPowered-up

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

Sail area / displacement 21.1
TenderStiff

38% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 38%

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