On Land 

With an electric motor in your sailboat, you no longer have to decide between sailing slowly with little wind, uncomfortable motor sailing, or calling it quits and firing up the diesel. Your motor is always on. You can use as little or as much power as the conditions call for. Motor sailing is where electric propulsion really shines.  A small amount of power goes a long way while you are under sail. It can help fill out your sails or point higher to get you to your destination faster.
