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.
Soft conditions suit it. 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 in light air, where it goes better than its measurements say it should. It holds that advantage cracked off as well, so the gain is not down to one leg of the course.
Where it pays
It falls short on a broad reach 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 0.4 kn either way.
At 10 knots this design makes back more than its rating asks on the upwind.
