Character

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

LivelySea-kindly

Her moderate displacement on a narrow beam gives 33 — a sea-kindly motion in a seaway.

Comfort ratio 33
CoastalBluewater

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

Capsize screening 1.76
LightHeavy

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

Displacement / length 250
EasygoingPowered-up

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

Sail area / displacement 18.2
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

A capable cruiser that sits just inside the offshore line — coastal work with real passages in her.
