Character

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

LivelySea-kindly

Her moderate displacement on a beamy beam gives 23 — a moderate, middle-of-the-road motion.

Comfort ratio 23
CoastalBluewater

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

Capsize screening 2.05
LightHeavy

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

Displacement / length 248
EasygoingPowered-up

14.3 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.3
TenderStiff

35% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 35%

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