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.

This is a light-air boat. In the light it does more than its numbers promise, and gives some of that back when the wind arrives.

Where it gains

Its best ground is on the beat once it pipes up, where it does more than its size and sail area promise, and by a margin worth having.

Where it pays

It falls short on a broad reach once it pipes up, giving away time it never gets back. That is weight that has to be driven rather than released.

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.
