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 42 — a heavy, notably soft motion offshore.

Comfort ratio 42
CoastalBluewater

At 1.68 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.68
LightHeavy

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

Displacement / length 318
EasygoingPowered-up

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

Sail area / displacement 13.8
TenderStiff

35% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 35%

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

  • Heavier than ~90% of boats her size on file

Compared with 1899 boats of the same type within a quarter of her length.
