Workmanship shown by sailor on current vessel (10)
I believe the answer is:
handicraft
'workmanship' is the definition.
(someone's craft or work)
'shown by sailor on current vessel' is the wordplay.
'shown by' says to put letters next to each other.
'sailor' becomes 'hand' (hand can mean a sailor or crew member).
'on current' becomes 'i' (symbol for electric current. I am not sure about the 'on' bit.).
'vessel' becomes 'craft' (synonyms).
'hand' next to 'i' is 'handi'.
'handi'+'craft'='HANDICRAFT'
Can you help me to learn more?
(Other definitions for handicraft that I've seen before include "manual skill" , "sewer's output perhaps" .)
