Entertaining place, an inspiration given to chaps likely to return aboard ship (9,4)
I believe the answer is:
amusement park
'entertaining place' is the definition.
'an inspiration given to chaps likely to return aboard ship' is the wordplay.
I cannot quite see how this works, but
'an' could be 'a' and 'a' is present in the answer.
'inspiration' could be 'muse' and 'muse' is located in the answer.
'chaps' could be 'men' (I've seen this before) and 'men' is present in the answer.
'ship' could be 'ark' (I've seen this in other clues) and 'ark' is located in the answer.
This explanation may well be incorrect...
(Other definitions for amusement park that I've seen before include "thrilling rides here" , "Alton Towers, for instance" , "Area with rides and other entertainments" , "Funfair" .)
