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 36 — a sea-kindly motion in a seaway.

Comfort ratio 36
CoastalBluewater

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

Capsize screening 1.75
LightHeavy

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

Displacement / length 350
EasygoingPowered-up

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

Sail area / displacement 12.9
TenderStiff

27% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 27%

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

Compared with 397 boats of the same type within a quarter of her length.
