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 one is at home going to windward. Windward-leeward courses give it more of what it is good at than a coastal race does.
Where it gains
Its best ground is upwind when it blows, where it does more than its size and sail area promise, and by a margin worth having.
Where it pays
It falls short off the wind 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 beam reach.
