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 30 — a sea-kindly motion in a seaway.

Comfort ratio 30
CoastalBluewater

At 1.65 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.65
LightHeavy

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

Displacement / length 363
EasygoingPowered-up

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

Sail area / displacement 13.4
TenderStiff

50% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 50%

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

  • Narrower than ~80% of boats her size on file

Compared with 304 boats of the same type within a quarter of her length.
