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 38 — a sea-kindly motion in a seaway.

Comfort ratio 38
CoastalBluewater

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

Capsize screening 1.72
LightHeavy

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

Displacement / length 424
TenderStiff

22% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 22%

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

  • Beamier than ~76% of boats her size on file

Compared with 427 boats of the same type within a quarter of her length.
