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

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 cracked off once it pipes up, where it goes better than its measurements say it should, 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 1.6 kn either way.
At 10 knots this design makes back more than its rating asks on the downwind.

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 690 kg.
Rigging
J/111 rig and sail dimensions
A J/111 carries 13.77 m of mainsail hoist on a 4.42 m boom, a forestay 14.74 m above the deck and a 6.65 m bowsprit. Typical figures across the 64 boats measured under the current VPP, with the range each one spans.
Rig
Sails
The spinnaker spreads widest of all — 121 to 144 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.
