The Solar Sailer is a vehicle in the Tron franchise. It is a simulation of a futuristic bulk transport vehicle. When idle, its sails are translucent; however, for faster speeds, the sails turn opaque and give the solar sailer a tremendous boost in speed. The sailer flies on (according to the script) "data transmission beams" that send information to other parts of a local computer. These beams could conduct power surges if the data stream is too strong and could cause immobility and slowly derez the sailer. If a power surge is encountered, the pilot must switch to a different beam via a junction immediately or the sailer will derez.
