Respectable

Respectable was an Imperial cruiser of unknown class that was a part of the blockade of ThonBoka. It functioned as a picket cruiser, challenging Lando Calrissian when he arrived at the blockade. Lando was brought aboard the vessel. He posed as a travelling salesman and gained the trust of a security chief onboard, who gave him contacts on other ships on the blockade he could sell his wares to.

Behind the scenes
The Respectable's over 200-meter hanger and closing hanger doors may imply that it was a Venator-class Star Destroyer or some variant.
