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 32 — a sea-kindly motion in a seaway.

Comfort ratio 32
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

337 — heavy for her waterline, built to carry stores and ride steadily.

Displacement / length 337
TenderStiff

43% of her weight is ballast — stiff, standing up well to her sails.

Ballast 43%

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

  • Draws less than ~78% of boats her size on file
  • Narrower than ~82% of boats her size on file

Compared with 2879 boats of the same type within a quarter of her length.
