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 46 — a heavy, notably soft motion offshore.

Comfort ratio 46
CoastalBluewater

At 1.57 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.57
LightHeavy

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

Displacement / length 338
EasygoingPowered-up

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

Sail area / displacement 13.5
TenderStiff

29% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 29%

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