Tug: A small craft, not even a kilometer in length, with only five thousand hands aboard. Ugly but functional. Of particular use to Inquisitors who might need their oversized realspace and warp engines to help move damaged or simply reluctant vessels somewhere more convenient. Their other use is that the (relatively) small crew for a warp capable vessel makes them much easier to crew with only trusted vassals.

11-20

Star Yacht: Sleek and ornate, the Star Yacht is designed to show off status and provide transport in style. Some are more designed for opulence than anything else, compromising armament and redundancy, while more practical (or paranoid) owners may have a very effective ship simply gilded. Regardless most will have reliable (if maintenance intensive) engines and powerful shields. Perfect for pow-wowing political big-wigs.

21-30

Herald/Relay Vessel: Designed for speed, relaying, and communications, this craft is mostly engines, astropaths, and data storage. Ideal for Inquisitorial business where time is of the essence, need to coordinate a large number of servants, or are in possession of large amounts of electronic information.

31-40

Pilgrim Ship/Passenger Liner: The Inquisitor may be undercover as passenger liner to monitor the population of a sub sector or they may simply need a large population of... subjects. Alternatively more pious individuals may be on a pilgrimage of their own and they decided to bring along a few thousand other such individuals, just in case.

41-50

Clipper Ship & Blockade Runners: Some of the fastest ships in the Imperium. They are designed to get small cargo and important passengers where they need to be. The difference between a clipper and a Blockade Runner is determined by the training of the crew and the weight of the armament, though both typically lack substantial armor.

51-60

Cargo Hauler: There are few ships more basic than these. Some Inquisitors like to have a lot of stuff where ever they go, and a cargo ship will certainly have the hold space to get almost anything they can acquire wherever they might want to go. Though the lack of armor and weapons might come back to bite the overly aggressive Inquisitor. As civilian ships have smaller crews and the large open holds that military ships lack, these vessels are better at hauling troops than smaller warships, quite handy for the Inquisitor on Crusade.

61-70

Armed Merchantmen/Q-Ship: Whilst all ships carry guns these carry more. Though they aren't proper warships they are far more capable than their fellows. An Inquisitor in possession of such a vessel will be able to move large amounts of personal and equipment quite cost effectively, and in relative safety. The difference between a Q-ship and an armed freighter is whether or not the weapons are hidden, as Q-ships are designed to ambush attackers expecting easy prey.

71-80

Refinery Ship/Factory Vessel: Such a ship is a common sight in Mechanicus fleets. Refinery ships collect ore and refine them into usable materials while factory ships can manufacture items on-demand, the better to maintain a steady supply on a crusade or exploration journey. An Inquisitor who uses this ship is usually tied to the Mechanicus or happened to come across one in his travels. Either way, he/she finds themselves having to visit a port to resupply less often.

81-90

Hospital Ship/Research Vessel: By virtue of mercy or pragmatism this ship has been outfitted with enough medical facilities to treat whole armies. The fact that this allows the Inquisition to monitor warzones for possible contamination by poison and disease is obvious, though whether the Inquisitor in question is trying to cure the blight or weaponize it for later might not be as much.

91-100

Exotic: Alien (exploration or transport vessel?), Mechanicus exploration vessel, Naval/Inquisitorial Reconnaissance (possibly with psychic wardings), Ministorum Cathedral ship, etc.
