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 38 — a sea-kindly motion in a seaway.

Comfort ratio 38
CoastalBluewater

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

Capsize screening 1.76
LightHeavy

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

Displacement / length 252
EasygoingPowered-up

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

Sail area / displacement 16.4
TenderStiff

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

Ballast 43%

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

  • Heavier than ~90% of boats her size on file
  • Draws less than ~78% of boats her size on file
  • Beamier than ~85% of boats her size on file

Compared with 2032 boats of the same type within a quarter of her length.
