Character

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

LivelySea-kindly

Her moderate displacement on a narrow beam gives 51 — a heavy, notably soft motion offshore.

Comfort ratio 51
CoastalBluewater

At 1.54 she sits well under the 2.0 line — a solidly ocean-capable hull for her size.

Capsize screening 1.54
LightHeavy

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

Displacement / length 208
EasygoingPowered-up

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

Sail area / displacement 23.8
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 ~95% of boats her size on file
  • Beamier than ~75% of boats her size on file

Compared with 274 boats of the same type within a quarter of her length.
