Character

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

LivelySea-kindly

Her heavy displacement on a narrow beam gives 39 — a sea-kindly motion in a seaway.

Comfort ratio 39
CoastalBluewater

At 1.69 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.69
LightHeavy

385 — very heavy for her waterline, a serious load-carrying cruiser.

Displacement / length 385
EasygoingPowered-up

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

Sail area / displacement 12.6
TenderStiff

39% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 39%

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

  • Heavier than ~81% of boats her size on file

Compared with 2686 boats of the same type within a quarter of her length.
