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

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

Capsize screening 1.70
LightHeavy

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

Displacement / length 122
EasygoingPowered-up

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

Sail area / displacement 21.3
TenderStiff

26% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 26%

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 ~86% of boats her size on file
  • Beamier than ~96% of boats her size on file

Compared with 122 boats of the same type within a quarter of her length.
