Sails don't collect nearly enough energy to move a ferry which is capable of moving hundreds of people and over 100 cars. What do you mean by recharging batteries using generators and using wind? If you mean turbines, keep in mind most turbines are hundreds of feet tall and their blades are extremely long. Overall, wind turbine technology is far, far too large for ships to utilize.
