Updated
The JPK 11.80 is a 11.82 m semi-displacement racing yacht designed by Jacques Valer and built by JPK Composites, first launched in 2018. It races in Class B. Across the measured fleet it goes better than its own numbers promise, ahead of 81% of the designs it races against.
Goes better than its own measurements promise, and does it better than 81% of the boats it races against.
18th of 92 in its class.
Updated — First Race Edge for this design. Enough boats of this design have now been measured to rank it. It is strongest in light and heavy air.
This design has been found in real race results — 75 starts across 14 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.

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.
This is a boat that wants breeze. Give it a fresh day and long legs and it delivers more than it promised; in a drifter it is working uphill.
Where it gains
Its best ground is cracked off in a strong breeze, where it does more than its size and sail area promise, and by a margin worth having. It holds that advantage on the run as well, so the gain is not down to one leg of the course.
Where it pays
There is no condition where it falls away badly, which is worth something over a season of mixed weather.
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 1.2 kn either way.
At 10 knots this design makes back more than its rating asks on the beam reach.
