Character

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

LivelySea-kindly

Her heavy displacement on a narrow beam gives 44 — a heavy, notably soft motion offshore.

Comfort ratio 44
CoastalBluewater

At 1.62 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.62
LightHeavy

299 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 299
EasygoingPowered-up

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

Sail area / displacement 14.9
TenderStiff

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

Ballast 43%

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

  • Heavier than ~81% of boats her size on file
  • Draws more than ~88% of boats her size on file

Compared with 230 boats of the same type within a quarter of her length.
