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 its best work before the breeze fills in. In the light it does more than its numbers promise, and gives some of that back when the wind arrives.
Where it gains
Its best ground is to windward in the light stuff, where it does more than its size and sail area promise. It holds that advantage across the wind as well, so the gain is not down to one leg of the course.
Where it pays
It falls short cracked off once it pipes up, giving away time it never gets back. That is weight that has to be driven rather than released.
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 0.4 kn either way.
At 10 knots this design makes back more than its rating asks on the upwind.

How they are set up
The range each sail spans across the fleet.
Nearly all carry a folding propeller. Crew weight is declared around 490 kg.
Rigging
X-342 rig and sail dimensions
A X-342 carries 13.15 m of mainsail hoist on a 4.70 m boom, a forestay 12.55 m above the deck and a 4.15 m bowsprit. Typical figures across the 5 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 65 to 73 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.
