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

Comfort ratio 24
CoastalBluewater

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

Capsize screening 1.76
LightHeavy

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

Displacement / length 273
EasygoingPowered-up

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

Sail area / displacement 15.2
TenderStiff

58% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 58%

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

  • Lighter than ~77% of boats her size on file
  • Narrower than ~82% of boats her size on file

Compared with 288 boats of the same type within a quarter of her length.
