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

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

Capsize screening 1.70
LightHeavy

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

Displacement / length 273
EasygoingPowered-up

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

Sail area / displacement 14.1
TenderStiff

32% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 32%

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

  • Heavier than ~87% of boats her size on file

Compared with 2626 boats of the same type within a quarter of her length.
