Cryptically, draws in a direction away from port (8)
I believe the answer is:
outwards
'cryptically' is the definition.
Both the definition and answer are adverbs. Maybe you can see an association between them that I don't see?
'draws in a direction away from port' is the wordplay.
I cannot quite see how this works, but
an anagram of 'draws' is 'wards' which is present in the answer.
'away' could be 'out' (similar in meaning) and 'out' is present in the answer.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for outwards that I've seen before include "Away from the centre" , "In an external direction" .)
