Reportedly went on courses, primarily to get waterborne vessel driving skills (9)
I believe the answer is:
roadcraft
'get waterborne vessel driving skills' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.
'reportedly went on courses primarily' is the wordplay.
'reportedly' shows a homophone (sound like).
'went on' becomes 'rode' (I've seen this in another clue).
'courses primarily' becomes 'craft' (I can't explain this - if you can you should give a lot more credence to this answer).
'rode' sounds like 'road'.
'road'+'craft'='ROADCRAFT'
'to' acts as a link.
Can you help me to learn more?
(Another definition for roadcraft that I've seen is " driving skill".)
