Yes, Jabba had his own ship. It was called the 'Star Jewel' and appeared in a variety of Expanded Universe (EU) sources including Star Wars: Dark Forces, in various books including the Han Solo Trilogy and some Star Wars comics.
As far as I'm aware, it's never been mentioned in a 'G-canon' source such as a TV show or film, nor is it even hinted-at in situations where it would theoretically have been of great use such as the sequence in Clone Wars where Jabba's son is kidnapped and taken off-world.
The ship itself bears a similarity to Jabba's sailbarge, including the sloped front, flattened rear and colour pattern (brown on brown). It apparently had a cloaking device and is described (in Darth Plageius) as;
"A space cruiser of gargantuan size and ostentatious design...Shaped
like an arrowhead, the vessel was heavily armed and large enough to
accommodate half a dozen starfighters."
