I modeled two sailboats with WindPlugin and then organized sailboat races. One boat on full sail and the other with loose sail. However, both boats are getting the same speed. How to make the strength of the wind acting on the boat depend on the sail's active cross-section on which the wind acts)?image description

There isn't anything built-in to take the sail's area into account, but you can write a custom plugin for the boat's dynamics. There is an example here that controls a boat's dynamics based on its size and other properties https://github.com/osrf/vrx/blob/mast...

The parameters are passed in here https://github.com/osrf/vrx/blob/mast... Another set of parameters for a different vehicle https://github.com/osrf/vorc/blob/mas...

Another example to look at is the LiftDragPlugin for aerodynamics http://gazebosim.org/tutorials?tut=ae...
