Character

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

Shoal draughtDraws 0.74 m, board up where she has one — creeks, sandbars and thin anchorages most keels have to stay out of.

LivelySea-kindly

Her moderate displacement on a moderate beam gives 29 — a moderate, middle-of-the-road motion.

Comfort ratio 29

CoastalBluewater

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

Capsize screening 1.96

LightHeavy

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

Displacement / length 242

EasygoingPowered-up

14.7 — modest power for her weight; easygoing rather than lively, and happier with a breeze.

Sail area / displacement 14.7

TenderStiff

35% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 35%

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

Beamier than ~81% of boats her size on file

Compared with 259 boats of the same type within a quarter of her length.

What the fleet has seen

The Ovni 435, as the fleet has seen it

Derived from the videos the fleet has analysed of this model. ▶ marks open the moment aboard.

The Ovni 435 is a 12.9-meter aluminum cutter designed by Philippe Briand and built by Chantier Alubat from 2004 to the present. It features a lifting keel and displaces 10,299 kg. Jon Amtrup, a Norwegian sailing journalist, previously owned an Ovni 435, citing its aluminum hull for ice resistance and superior insulation, which kept the interior warm at minus 20°C. Amtrup, who sails year-round, heated his boat with a Refleks diesel stove.
