How do I trace a ship called Liverpool

[seaweed]

Further to my last post, I have found that Tobin and Co were a leading shipping company in Liverpool who's main business was concentrated on the African trade.
Logically, why would a ship bearing the name LIVERPOOL be registered in Hull?
If you don't get a positive result from Hull History Centre try an email to Liverpool Maritime Museum
maritime@liverpoolmuseums.org.uk
If they can confirm the ship LIVERPOOL was in fact registered in Liverpool. You can then go on to look at the Muster Roles at TNA Kew. A visit would be the best way to view.
