Report a regattaRound the buoys, or offshore
A short windward-leeward and a night at sea ask different things of a boat. Here is how this one does in each.

Sharper round the buoys. Short courses reward acceleration and manoeuvring, and that is where this design makes its money.

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 does most things without giving much away. It rewards preparation and crew work more than it rewards picking the right day.
Where it gains
Its best ground is on a reach once it pipes up, where it outruns what it looks like on paper, and by a margin worth having.
Where it pays
It falls short on the run when it blows, giving away time it never gets back. That is a displacement hull working to its designed speed.
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 0.6 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 450 kg.
Rigging
Dufour 350 rig and sail dimensions
A Dufour 350 carries 12.03 m of mainsail hoist on a 4.50 m boom, a forestay 12.60 m above the deck and a 4.44 m bowsprit. Typical figures across the 3 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 72 to 95 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.
