Skilled trades in building boats (6)
I believe the answer is:
crafts
'skilled trades' is the definition.
(I've seen this before)
'building boats' is the wordplay.
'building' becomes 'c' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'boats' becomes 'rafts' (I have seen 'Flat boats ' mean 'rafts' so perhaps 'boats' could also mean 'rafts').
'c'+'rafts'='CRAFTS'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for crafts that I've seen before include "Skilled trades" , "Builds" , "Occupations requiring special skills" , "Boats; skills" , "Hand-made objects" .)
