Haul fish up away from the wind (7)
I believe the answer is:
leeward
'away from the wind' is the definition.
(as in the lee side of a river)
'haul fish up' is the wordplay.
'haul' becomes 'draw' (synonyms).
'fish' becomes 'eel' (eel is a kind of fish).
'up' shows that the letters should be reversed in order (in down clue: letters go upwards).
'draw'+'eel'='draweel'
'draweel' written backwards gives 'LEEWARD'.
(Other definitions for leeward that I've seen before include "Towards the sheltered side" , "Draw eel (anag.)" , "On sice turned away from wind" , "A welder (anag.)" , "Of ship, on side turned away from wind" .)
