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 41 — a heavy, notably soft motion offshore.

Comfort ratio 41
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

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

Displacement / length 238
EasygoingPowered-up

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

Sail area / displacement 14.2
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 ~90% of boats her size on file
