When the wind doubles does the pressure in the sails increase 8 times?
When the apparent wind speed is doubled, the pressure on the sail is quadrupled. That is because the pressure on the sail (or the side of your house or a billboard sign) is proportional to the square of the speed of the wind. If the wind speed triples, then the pressure goes up by a factor of nine, because three squared is nine.
