Pressure confuses crew on Queen Elizabeth and another vessel (6,7)
I believe the answer is:
paddle steamer
'vessel' is the definition.
(paddle steamer is a kind of vessel)
'pressure confuses crew on queen elizabeth' is the wordplay.
'pressure' becomes 'p' (abbreviation).
'confuses' becomes 'addles' (addling is a kind of confusing).
'crew on' becomes 'team' (I've seen this before. I am not sure about the 'on' bit.**).
'queen elizabeth' becomes 'er' (abbreviation for Elizabeth Regina).
'p'+'addles'+'team'+'er'='PADDLE-STEAMER'
'and another' is the link.
Can you help me to learn more?
(Other definitions for paddle steamer that I've seen before include "Type of ship" , "Mississippi boat?" , "Ship propelled by bladed wheels" , "River boat, for example" , "vessel" .)
