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

Comfort ratio 24
CoastalBluewater

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

Capsize screening 1.79
LightHeavy

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

Displacement / length 251
EasygoingPowered-up

16.0 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 16.0
TenderStiff

46% of her weight is ballast — stiff, standing up well to her sails.

Ballast 46%

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

  • Narrower than ~84% of boats her size on file

Compared with 1547 boats of the same type within a quarter of her length.
