Crossword Genius

With U-boats manoeuvring in, change tack (5-4)

Ross

I believe the answer is:

about-ship

'change tack' is the definition.
(about-ship means to move a ship onto a new tack)

'with u-boats manoeuvring in' is the wordplay.
'with' means one lot of letters goes inside another.
'manoeuvring' indicates an anagram.
'in' becomes 'hip' (both can mean fashionable).
'boats' with letters rearranged gives 'abots'.
'u' going inside 'abots' is 'abouts'.
'abouts'+'hip'='ABOUT-SHIP'

(Another definition for about-ship that I've seen is " command on galley, say".)

I've seen this clue in The Times.
