Character

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

LivelySea-kindly

Her heavy displacement on a moderate beam gives 48 — a heavy, notably soft motion offshore.

Comfort ratio 48
CoastalBluewater

At 1.58 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.58
LightHeavy

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

Displacement / length 354
EasygoingPowered-up

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

Sail area / displacement 17.3
TenderStiff

31% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 31%

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

  • Heavier than ~91% of boats her size on file
  • Draws more than ~94% of boats her size on file
  • Beamier than ~76% of boats her size on file

Compared with 317 boats of the same type within a quarter of her length.
