The Volitan is a Star Wars-esque sail boat design by Designnobis Studio that utilizes solid wind sails and solar energy at the same time. The energy that’s harnessed from the solar panels and wind turbine are stored in a battery that can be utilized throughout the day and night. The wings actually track the sun and wind for optimal performance and in extreme whether conditions they fold up against the side of the boat. Since the Volitan is engineered to operate in winds of up to 60 knots, you’re pretty much screwed if the wings run and hide.  But if you do need to move without the sails the motors on both sides of the boat allow the Volitan to maneuver like Bryan Boitano on a cold day.
