Round 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.

Speed in knots at 20 knots of true wind. Green marks the angles that pay: the closest useful beat and the deepest run worth sailing.

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.

The stronger it blows, the better this design looks. 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

It falls short upwind in a strong breeze, giving away time it never gets back. That is a hull that wants to get up and go, and needs pressure to do it.

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.

At 10 knots this design makes back more than its rating asks on the broad reach.
