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 39 — a sea-kindly motion in a seaway.

Comfort ratio 39
CoastalBluewater

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

Capsize screening 1.70
LightHeavy

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

Displacement / length 220
EasygoingPowered-up

18.5 — plenty of sail for her weight; lively and quick to respond.

Sail area / displacement 18.5
TenderStiff

33% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 33%

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

  • Heavier than ~91% of boats her size on file
  • Draws more than ~83% of boats her size on file
  • Beamier than ~81% of boats her size on file

Compared with 1601 boats of the same type within a quarter of her length.
