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 30 — a sea-kindly motion in a seaway.

Comfort ratio 30
CoastalBluewater

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

Capsize screening 1.78
LightHeavy

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

Displacement / length 273
EasygoingPowered-up

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

Sail area / displacement 14.5
TenderStiff

41% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 41%

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

  • Heavier than ~77% of boats her size on file

Compared with 2631 boats of the same type within a quarter of her length.
