Character

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

LivelySea-kindly

Her heavy displacement on a moderate beam gives 37 — a sea-kindly motion in a seaway.

Comfort ratio 37
CoastalBluewater

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

Capsize screening 1.78
LightHeavy

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

Displacement / length 341
EasygoingPowered-up

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

Sail area / displacement 14.8
TenderStiff

36% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 36%

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

  • Heavier than ~87% of boats her size on file
  • Draws less than ~88% of boats her size on file
  • Beamier than ~76% of boats her size on file

Compared with 2742 boats of the same type within a quarter of her length.
