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 36 — a sea-kindly motion in a seaway.

Comfort ratio 36
CoastalBluewater

At 1.64 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.64
LightHeavy

317 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 317
EasygoingPowered-up

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

Sail area / displacement 16.5
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.

  • Narrower than ~82% of boats her size on file

Compared with 2845 boats of the same type within a quarter of her length.
