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 most things without giving much away. It rewards preparation and crew work more than it rewards picking the right day.
Where it gains
Its best ground is off the wind when it blows, where it outruns what it looks like on paper, and by a margin worth having. It holds that advantage to windward as well, so the gain is not down to one leg of the course.
Where it pays
It falls short on the beam in a strong breeze, giving away time it never gets back. That is weight that has to be driven rather than released.
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 0.6 kn either way.
At 10 knots this design makes back more than its rating asks on the upwind.
