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.

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

It features a fin keel with a rudder on skeg, a 4.5-meter beam, a 2.4-meter draft, and displaces 18,999 kg. In 2008, the model was rebranded as part of the Aphrodite series.
