Updated — First Race Edge for this design. Enough boats of this design have now been measured to rank it. It is strongest in light, medium and heavy air.

Not verified. On planing hulls this score has no match in the race results we hold: designs scoring the same win anywhere from one race in ten to seven in ten. Read it as what the measurements say, not as a ranking.

This design has been found in real race results — 18 starts across 1 event — not only in measurement files.

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 the run when it blows, where it goes better than its measurements say it should, and by a margin worth having. It holds that advantage cracked off 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.
