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.

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 on a reach once the breeze fills, where it does more than its size and sail area promise, 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 to windward when the breeze is soft, giving away time it never gets back.

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.
