Water shortage restricts Dane moving boat (11)
I believe the answer is:
dreadnought
'boat' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe there's an association between them I don't understand?
'water shortage restricts dane moving' is the wordplay.
'water shortage' becomes 'drought' (I've seen this before).
'restricts' is an insertion indicator.
'moving' indicates anagramming the letters (letters are moved around).
'dane' with letters rearranged gives 'eadn'.
'drought' placed around 'eadn' is 'DREADNOUGHT'.
Can you help me to learn more?
(Other definitions for dreadnought that I've seen before include "Vessel" , "Old warship" , "Early twenieth century battleship" , "Large battleship" , "Revolutionary British battleship (1906) - first British nuclear-powered submarine (1963)" .)
