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.
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 on a broad reach when it blows, where it outruns what it looks like on paper, and by a margin worth having. It holds that advantage on a reach 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 broad 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 680 kg.
Rigging
More 40 rig and sail dimensions
A More 40 carries 15.80 m of mainsail hoist on a 5.55 m boom, a forestay 16.00 m above the deck and a 5.10 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 — 133 to 177 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.
