Updated
The JPK 10.10 is a 10.04 m semi-displacement racing yacht designed by Jacques Valer and built by JPK Composites, first launched in 2010. It races in Class C. Across the measured fleet it goes better than its own numbers promise, ahead of 64% of the designs it races against. It comes alive as the breeze builds, and gives time away in the light.
Goes better than its own measurements promise, and does it better than 64% of the boats it races against.
58th of 159 in its class.
This design has been found in real race results — 14 starts across 10 events — not only in measurement files.

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.
The stronger it blows, the better this design looks. 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 goes better than its measurements say it should, and by a margin worth having. It holds that advantage running deep 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 0.8 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.
Nearly all carry a folding propeller. A bowsprit is standard across the fleet. Crew weight is declared around 570 kg.
Rigging
JPK 10.10 rig and sail dimensions
A JPK 10.10 carries 12.56 m of mainsail hoist on a 4.25 m boom, a forestay 13.07 m above the deck and a 4.43 m bowsprit. Typical figures across the 8 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 69 to 106 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.
