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 36 — a sea-kindly motion in a seaway.

Comfort ratio 36
CoastalBluewater

At 1.56 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.56
LightHeavy

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

Displacement / length 361
EasygoingPowered-up

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

Sail area / displacement 14.9
TenderStiff

34% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 34%

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

  • Narrower than ~75% of boats her size on file

Compared with 423 boats of the same type within a quarter of her length.
