Ship worker in charge on floating platform shows workmanship (10)
I believe the answer is:
handicraft
'workmanship' is the definition.
(someone's craft or work)
'ship worker in charge on floating platform' is the wordplay.
'ship worker' becomes 'hand' (I can't explain this - if you can you should give a lot more credence to this answer).
'in charge' becomes 'ic' (abbreviation for 'in charge').
'on' says to put letters next to each other.
'floating platform' becomes 'raft' (I've seen this in another clue).
'hand'+'ic'+'raft'='HANDICRAFT'
'shows' is the link.
Can you help me to learn more?
(Other definitions for handicraft that I've seen before include "sewer's output perhaps" , "manual skill" .)
