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 43 — a heavy, notably soft motion offshore.

Comfort ratio 43
CoastalBluewater

At 1.68 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.68
LightHeavy

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

Displacement / length 239
EasygoingPowered-up

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

Sail area / displacement 15.3
TenderStiff

30% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 30%

A capable offshore cruiser with an easy motion when the sea gets up.

  • Heavier than ~92% of boats her size on file
  • Beamier than ~86% of boats her size on file
