Solar sailer

Solar sailers were a method of propulsion used by some starships. Although called "solar" sailers, they were more commonly propelled by tachyon streams and ultraviolet lasers rather than the photons and "solar wind" (high-energy plasma which escaped a star's gravity) of sunlight. Gathered on a sufficiently large surface (solar sails would unfurl to colossal diameters, rivaling the surface area of moons), the absorbed momentum would then accelerate the spacecraft. Once optimal velocity had been reached, the hyperdrive motivator would kick in and allow the craft to enter hyperspace.

Count Dooku had a one-of-a-kind solar sail procured from the Gree Enclave fitted to his Punworcca 116-class interstellar sloop, which he used as his personal transport prior to and during the Clone Wars. Very small for a sailer, with a sail of exotic matter powered by mysterious undetectable energies, Dooku's interstellar sloop was one of the most unique craft in the galaxy.
