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

Comfort ratio 21
CoastalBluewater

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

Capsize screening 2.00
LightHeavy

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

Displacement / length 222
EasygoingPowered-up

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

Sail area / displacement 18.3
TenderStiff

49% of her weight is ballast — stiff, standing up well to her sails.

Ballast 49%

A balanced, easily-driven cruiser — comfortable and forgiving for coastal work.
