if a ship moving to South and wind is flowing due West(at given velocities),we can find the angle by which the ship is deviated.Does here momenta of wind and ship matters?If it had been water at same velocity instead of wind, what would have happened?....
You would need more information to predict the effect of the wind upon deviating the ship. For a sailboat, the force due to the wind depends very much upon how the sails are set.
