Updated
The X-412 is a 12.49 m heavy displacement racing yacht designed by Niels Jeppesen and built by X-Yachts, first launched in 1990. It races in Class B. Across the measured fleet it goes better than its own numbers promise, ahead of 25% of the designs it races against. It is at its best in light air and struggles to hold that once it blows.
Goes better than its own measurements promise, and does it better than 25% of the boats it races against.
69th of 92 in its class.
This design has been found in real race results — 69 starts across 30 events — not only in measurement files.

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

Better the longer it gets. Boats that settle into a groove and hold it gain ground once the course stops turning.

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 is an upwind boat first. Windward-leeward courses give it more of what it is good at than a coastal race does.
Where it gains
Its best ground is to windward once it pipes up, where it does more than its size and sail area promise, and by a margin worth having.
Where it pays
It falls short cracked off when it blows, 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 670 kg.
Rigging
X-412 rig and sail dimensions
A X-412 carries 14.39 m of mainsail hoist on a 4.70 m boom, a forestay 16.43 m above the deck and a 5.13 m bowsprit. Typical figures across the 32 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 96 to 130 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.
