161 — light for her waterline, so she is easily driven and quick to accelerate.

Displacement / length 161

EasygoingPowered-up

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

Sail area / displacement 22.9

TenderStiff

38% of her weight is ballast — moderately stiff, a middle-of-the-road stability.
