Go to liverpool Dock there is plenty to see museums ect
when you have had enough of that you can take a ferry trip across the mersy to the other site if you get off and walk down the road a bit there is a ship yard you cant miss it there is a big German Submarine in the front area

2 subs a distroyer and other ships you can look round its not a guided tour and you can spend all day going round them
i think its £5 to enter the dock but all the ships and one of the subs are free H.M.S.ONYX is the sub its realy good
The big German sub has to be booked in advance to go round it
