Report a regattaRound the buoys, or offshore
A short windward-leeward and a night at sea ask different things of a boat. Here is how this one does in each.

Level across both. Plenty of designs fall away once the course gets long — a light hull that thrives round the cans can struggle through a night at sea. This one does not.

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.
Reaching and running is where this one pays. A course with long free legs suits it better than a windward-leeward.
Where it gains
Its best ground is cracked off when it blows, where it goes better than its measurements say it should, and by a margin worth having. It holds that advantage on the run as well, so the gain is not down to one leg of the course.
Where it pays
It falls short to windward in a strong breeze, giving away time it never gets back. That is a hull that will lift and run given enough breeze.
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 broad reach.
