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.
It does its best work before the breeze fills in. In the light it does more than its numbers promise, and gives some of that back when the wind arrives.
Where it gains
Its best ground is upwind 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 beam as well, so the gain is not down to one leg of the course.
Where it pays
It falls short off the wind when it blows, giving away time it never gets back. That is a hull that will lift and run given enough breeze.
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 1.0 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 1110 kg.

X-612 rig and sail dimensions
A X-612 carries 21.67 m of mainsail hoist on a 7.09 m boom, a forestay 24.03 m above the deck and a 7.83 m bowsprit. Typical figures across the 2 boats measured under the current VPP, with the range each one spans.
