A sail barge delivers Jabba the Hutt and his entourage to the sarlacc pit in Return of the Jedi. Illustrator Ralph McQuarrie designed the ship to appear more utilitarian in comparison to early designs, which made the ship reminiscent of a Baroque sea craft. Joe Johnston continued working on the design after McQuarrie stepped away from the project. A full-scale sail barge set was erected in Yuma, Arizona; it was one of the largest Star Wars sets created. Measuring 150 feet long, 130 feet wide and 65 feet high, the sail barge set was supported by 130 wooden posts, each 27 feet high, which were deeply embedded into the ground. Underneath the barge were several offices and a commissary which could feed 150 people. In order to get to the set, a two-mile road made of compacted sand was built, requiring roughly 80,000 gallons of water to construct. According to Star Wars references, Jabba's sail barge is named the Khetanna and was built by Ubrikkian Industries as a pleasure barge for the crime lord. At long, it is powered by a repulsorlift engine to reach a maximum speed of but can also use its two sails to slowly travel by air power. While designed purely as a pleasure barge, the Khetanna is fitted with a laser cannon turret and heavy blasters can be mounted on the railings. Landspeeder Landspeeders are antigravity vehicles that appear throughout the films and Expanded Universe in both civilian and military roles. They appear in Star Wars: Episode IV – A New Hope. Sandcrawler C-3PO (Anthony Daniels) and R2-D2 (Kenny Baker) are briefly held in a Jawa sandcrawler in Star Wars Episode IV: A New Hope. Shots of the sandcrawler at a distance were actually a matte painting; only two of its treads and a 27-meter-long piece of its lower structure were actually built. For shots involving the vehicle's movement, ILM used a 125-centimeter radio-controlled model. A computer-generated sandcrawler briefly appears in The Phantom Menace, and a sandcrawler also appears in Attack of the Clones. Sandcrawler-related merchandise include a Lego model, card game items, and Hasbro and Micro Machines toys. Skyhopper An Incom Corporation T-16 skyhopper appears in the background of the Lars residence in A New Hope, and Luke Skywalker (Mark Hamill) races a skyhopper in National Public Radio's radio adaptation of that movie; a skyhopper also appears at the end of the Special Edition
