Character

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

LivelySea-kindly

Her light displacement on a moderate beam gives 25 — a moderate, middle-of-the-road motion.

Comfort ratio 25
CoastalBluewater

2.02 — right around the 2.0 line, the edge between coastal and offshore.

Capsize screening 2.02
LightHeavy

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

Displacement / length 169
EasygoingPowered-up

16.7 — moderate power for her weight; steady, all-round performance.

Sail area / displacement 16.7
TenderStiff

28% of her weight is ballast — on the tender side; she'll heel readily and want a reef sooner.

Ballast 28%

Light and lively — happiest day-sailing and coastal-hopping in settled weather.

What the fleet has seen

The Dufour Yachts 450 Grand Large, as the fleet has seen it

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

The Dufour Yachts 450 GRAND LARGE is a fractional sloop with a fin keel, bulb, and dual rudders, designed by Umberto Felci and built by Dufour Yachts from 2014 onward. It measures 13.5 meters LOA, with a 4.3-meter beam and a 2.2-meter draft, displacing 10,274 kg. Modern production sailboats, including models like the 450 GRAND LARGE, often feature cabin soles made from multiple small, screwed-down panels that can squeak and show fastener corrosion.1:39 Backstay-less rigs with raked spreaders, common on newer designs, limit downwind sail trim and complicate mast tuning.2:53 Integrated bowsprits, while accommodating code zero sails, can prevent the use of high-performance anchors like the Rocna or Mantis, forcing owners to consider proprietary anchors or boats with traditional bow rollers.7:48
