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 50 — a heavy, notably soft motion offshore.

Comfort ratio 50
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

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

Displacement / length 368
EasygoingPowered-up

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

Sail area / displacement 17.4
TenderStiff

36% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 36%

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

  • Heavier than ~95% of boats her size on file
  • Beamier than ~83% of boats her size on file

Compared with 1489 boats of the same type within a quarter of her length.
