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 25 — a moderate, middle-of-the-road motion.

Comfort ratio 25
CoastalBluewater

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

Capsize screening 1.89
LightHeavy

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

Displacement / length 288
EasygoingPowered-up

22.4 — a lot of sail for her weight; powered-up and eager, a real performer.

Sail area / displacement 22.4
TenderStiff

41% of her weight is ballast — moderately stiff, a middle-of-the-road stability.

Ballast 41%

Powered-up and quick to accelerate — this one likes to sail.
