Draw in net at sea, getting chill (6)
I believe the answer is:
entice
'draw in' is the definition.
(I've seen this in another clue)
'net at sea getting chill' is the wordplay.
'at sea' indicates anagramming the letters.
'getting' is a charade indicator (letters next to each other).
'chill' becomes 'ice' (icing is a kind of chilling).
'net' with letters rearranged gives 'ent'.
'ent'+'ice'='ENTICE'
(Other definitions for entice that I've seen before include "Attract, tempt" , "Attract with inducement" , "Attract with offers" , "alluring" , "'Tempt, lure (6)'" .)
