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 31 — a sea-kindly motion in a seaway.

Comfort ratio 31
CoastalBluewater

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

Capsize screening 1.77
LightHeavy

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

Displacement / length 256
EasygoingPowered-up

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

Sail area / displacement 12.6
TenderStiff

44% of her weight is ballast — stiff, standing up well to her sails.

Ballast 44%

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