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 52 — a heavy, notably soft motion offshore.

Comfort ratio 52
CoastalBluewater

At 1.63 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.63
LightHeavy

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

Displacement / length 432
EasygoingPowered-up

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

Sail area / displacement 11.2
TenderStiff

28% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 28%

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

  • Heavier than ~97% of boats her size on file
  • Draws less than ~88% of boats her size on file
  • Beamier than ~88% of boats her size on file

Compared with 1747 boats of the same type within a quarter of her length.
