Rule Of Thumb #3

The amount of gain or loss is proportional to the distance between boats..

The amount of gain or loss in a windshift is also affected by the distance (or "separation") between you and your competitors. The farther two boats are apart, the greater will be the relative gain and loss between them when the wind shifts. In the example at right, the wind has shifted 15 degrees in favor of Boat A. Because Boat C is twice as far from A as Boat B, Boat C will lose twice as much distance due to the windshift.
