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

Comfort ratio 20
CoastalBluewater

2.07 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.07
LightHeavy

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

Displacement / length 191
EasygoingPowered-up

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

Sail area / displacement 18.6
TenderStiff

34% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 34%

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