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 39 — a sea-kindly motion in a seaway.

Comfort ratio 39
CoastalBluewater

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

Capsize screening 1.74
LightHeavy

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

Displacement / length 364
EasygoingPowered-up

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

Sail area / displacement 11.7
TenderStiff

21% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 21%

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

  • Heavier than ~76% of boats her size on file
  • Draws less than ~79% of boats her size on file
  • Beamier than ~83% of boats her size on file

Compared with 306 boats of the same type within a quarter of her length.
