Arab sailor with a measure of intelligence (5)

I believe the answer is:

tariq

'arab' is the definition.
(common Arab name)

'sailor with a measure of intelligence' is the wordplay.
'sailor' becomes 'tar' (slang term for a sailor).
'with' means one lot of letters go next to another.
'a measure of intelligence' becomes 'IQ'.
'tar'+'iq'='TARIQ'

(Another definition for tariq that I've seen is " Arabic night visitor's name".)

I've seen this clue in The Times.
