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

Comfort ratio 25
CoastalBluewater

At 1.64 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.64
LightHeavy

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

Displacement / length 259
EasygoingPowered-up

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

Sail area / displacement 14.2
TenderStiff

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

Ballast 58%

Built heavy and sea-kindly — a boat made to cross oceans and forgive a rough night.

  • Lighter than ~80% of boats her size on file
  • Draws less than ~82% of boats her size on file
  • Narrower than ~98% of boats her size on file

Compared with 2569 boats of the same type within a quarter of her length.
