A skyship was a type of sports craft manufactured by OmoTact Corporation. There were several varieties, ranging in size from seven to fifteen meters, and required between eight and twenty sailors to crew. The hulls were double walled and made of an ulta light desh–terenthium alloy. The space between the hull was filled with heglum, a synthetic gas. They featured masts and sails for speed and directional movement. All skyskips on Bespin were equipped with Ponrez/Arc repulsorlift engines built by Bespin Motors in case of a lack of breeze to operate the sails. One model of skyship was the Roahks 7m Skyship.
