Not verified. On planing hulls this score has no match in the race results we hold: designs scoring the same win anywhere from one race in ten to seven in ten. Read it as what the measurements say, not as a ranking.
This design has been found in real race results — 27 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.
This is a boat that wants breeze. On a windy coastal course it is in its element; on a light-air windward-leeward it has to be sailed well to hold on.
Where it gains
Its best ground is on a broad reach in a strong breeze, where it outruns what it looks like on paper, 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 2.2 kn either way.
At 10 knots this design makes back more than its rating asks on the downwind.

Rigging
Mat 11.80 rig and sail dimensions
A Mat 11.80 carries 15.95 m of mainsail hoist on a 5.18 m boom, a forestay 15.77 m above the deck and a 6.55 m bowsprit. Typical figures across the 7 boats measured under the current VPP, with the range each one spans.

Sails
The spinnaker spreads widest of all — 160 to 178 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.
