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 35 — a sea-kindly motion in a seaway.

Comfort ratio 35
CoastalBluewater

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

Capsize screening 1.76
LightHeavy

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

Displacement / length 227
EasygoingPowered-up

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

Sail area / displacement 14.4
TenderStiff

26% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 26%

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

  • Heavier than ~84% of boats her size on file

Compared with 2432 boats of the same type within a quarter of her length.
