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 19 — a quick, lively motion that feels every wave.

Comfort ratio 19
CoastalBluewater

2.28 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.28
LightHeavy

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

Displacement / length 200
EasygoingPowered-up

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

Sail area / displacement 25.2
TenderStiff

57% of her weight is ballast — very stiff, carrying full sail in a blow.

Ballast 57%

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

  • Beamier than ~80% of boats her size on file
