Character

Where this design lands on the numbers a shopper trusts — read straight from her own ratios.

LivelySea-kindly

Her heavy displacement on a moderate beam gives 37 — a sea-kindly motion in a seaway.

Comfort ratio 37
CoastalBluewater

1.71 — just under the 2.0 offshore line; her beam is modest for her weight.

Capsize screening 1.71
LightHeavy

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

Displacement / length 402
EasygoingPowered-up

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

Sail area / displacement 12.1
TenderStiff

38% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 38%

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

  • Heavier than ~77% of boats her size on file
  • Draws less than ~82% of boats her size on file

Compared with 2956 boats of the same type within a quarter of her length.
