Character

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

LivelySea-kindly

Her moderate displacement on a narrow beam gives 40 — a heavy, notably soft motion offshore.

Comfort ratio 40
CoastalBluewater

At 1.61 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.61
LightHeavy

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

Displacement / length 254
EasygoingPowered-up

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

Sail area / displacement 13.8
TenderStiff

27% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 27%

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

  • Heavier than ~84% of boats her size on file
  • Draws less than ~93% of boats her size on file

Compared with 2267 boats of the same type within a quarter of her length.
