Great Ship
From Wookieepedia, the Star Wars wiki.
The Great Ship was a city-ship, a nautical vessel the size of a city. It was the only artificial structure on Drexel II, apart from the homes of the Dragon Lords.
[edit] History
It was constructed by outlaws on the run from the Galactic Republic, who had crashed their ship on the water-planet. Their space cruiser became the basis for the sea-going vessel, and as more wood-like material was harvested from the ocean-floor, the ship grew to enormous proportions. Several decades after first arriving on Drexel II, the colonists had made their own society on-board the vessel. They would use their Sonic Jammer to disrupt any spacecraft that entered the system, causing them to crash and plundering the wreckage.
The city-ship was damaged during the Battle of Drexel II, which saw the Dragon Lords victorious against the city-ship-dwellers.
The city-ship was about the same size as Crimson Jack's battlecruiser.
