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.

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 does its best work before the breeze fills in. Early-season racing and morning breezes play to its strengths; once it pipes up the fleet comes back to it.

Where it gains

Its best ground is cracked off in the light stuff, where it does more than its size and sail area promise, and by a margin worth having. It holds that advantage running deep as well, so the gain is not down to one leg of the course.

Where it pays

It falls short on a reach when it blows, giving away time it never gets back. That is a displacement hull working to its designed speed.

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.
