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 41 — a heavy, notably soft motion offshore.

Comfort ratio 41
CoastalBluewater

At 1.54 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.54
LightHeavy

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

Displacement / length 417
EasygoingPowered-up

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

Sail area / displacement 12.8

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

  • Draws more than ~94% of boats her size on file
