Character

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

Shoal draftDraws 1.17 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.
LivelySea-kindly

Her heavy displacement on a narrow beam gives 35 — a sea-kindly motion in a seaway.

Comfort ratio 35
CoastalBluewater

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

Capsize screening 1.72
LightHeavy

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

Displacement / length 439
EasygoingPowered-up

15.1 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 15.1
TenderStiff

29% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 29%

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

  • Heavier than ~75% of boats her size on file

Compared with 327 boats of the same type within a quarter of her length.
