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

Comfort ratio 26
CoastalBluewater

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

Capsize screening 1.87
LightHeavy

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

Displacement / length 246
EasygoingPowered-up

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

Sail area / displacement 22.1
TenderStiff

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

Ballast 42%

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