With embarrassed look, see ship manoeuvring at entrance to harbour (8)
I believe the answer is:
sheepish
'with embarrassed look' is the definition.
(sheepish can mean looking embarrassed)
'see ship manoeuvring at entrance to harbour' is the wordplay.
'manoeuvring' is an anagram indicator.
'at' is a charade indicator (letters next to each other).
'entrance to' says to take the initial letters.
The first letter of 'harbour' is 'h'.
'see'+'ship'='seeship'
'seeship' is an anagram of 'sheepis'.
'sheepis'+'h'='SHEEPISH'
(Other definitions for sheepish that I've seen before include "describing 3 [ROMNEY] ?" , "Embarrassed, looking silly" , "Embarrassed in woolly way?" , "embarrassment" , "Shy, shamefaced" .)
