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 43 — a heavy, notably soft motion offshore.

Comfort ratio 43
CoastalBluewater

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

Capsize screening 1.70
LightHeavy

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

Displacement / length 339
EasygoingPowered-up

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

Sail area / displacement 13.1
TenderStiff

35% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 35%

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

  • Heavier than ~93% of boats her size on file
  • Beamier than ~83% of boats her size on file

Compared with 1961 boats of the same type within a quarter of her length.
