A short windward-leeward and a night at sea ask different things of a boat. Here is how this one does in each.

Where it wins and where it pays
Every boat is judged against its own measurements — length, weight, sail area. The quicker those say it should be, the more it has to deliver just to break even. Going fast is not enough: it has to go faster than its own numbers promised.
It needs pressure to show what it can do. On a windy coastal course it is in its element; on a light-air windward-leeward it has to be sailed well to hold on.
Where it gains
Its best ground is on the beam in a working breeze, where it outruns what it looks like on paper, and by a margin worth having.
Where it pays
It falls short upwind in light air, giving away time it never gets back.
Above the line it delivers more than promised and gains on the fleet. Below, it falls short. Move the wind: plenty of boats sit on one side in the light and the other when it blows.
Full width is 1.0 kn either way.
At 10 knots this design makes back more than its rating asks on the beam reach.

How they are set up
The range each sail spans across the fleet.
Roughly half carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 810 kg.
Rigging
Dufour 430 rig and sail dimensions
A Dufour 430 carries 15.92 m of mainsail hoist on a 5.10 m boom, a forestay 16.41 m above the deck and a 5.39 m bowsprit. Typical figures across the 2 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 97 to 147 m² depending on bowsprit and set-up. Before ordering a sail, read the figure on your own measurement record rather than the typical one for the design.
