Character

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

LivelySea-kindly

Her moderate displacement on a moderate beam gives 36 — a sea-kindly motion in a seaway.

Comfort ratio 36
CoastalBluewater

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

Capsize screening 1.70
LightHeavy

270 — moderately heavy for her waterline, a balanced cruising weight.

Displacement / length 270
EasygoingPowered-up

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

Sail area / displacement 16.9

42% of her weight is ballast — stiff, standing up well to her sails.

Ballast 42%

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