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

Better the longer it gets. Boats that settle into a groove and hold it gain ground once the course stops turning.

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 needs pressure to show what it can do. 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 does more than its size and sail area promise, 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
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 1.0 kn either way.
At 10 knots this design makes back more than its rating asks on the broad reach.
