Character

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

LivelySea-kindly

Her light displacement on a narrow beam gives 41 — a heavy, notably soft motion offshore.

Comfort ratio 41
CoastalBluewater

At 1.65 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.65
LightHeavy

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

Displacement / length 161
EasygoingPowered-up

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

Sail area / displacement 28.0
TenderStiff

27% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 27%

A capable offshore cruiser with an easy motion when the sea gets up.

  • Heavier than ~84% of boats her size on file

Compared with 245 boats of the same type within a quarter of her length.
