'build boat' is the definition.
'craft' can be an answer for 'boat' (thesaurus). I am unsure of the 'build' bit.

'build boat' is the wordplay.
'build' becomes 'c' (I can't explain this - if you can you should give a lot more credence to this answer).
'boat' becomes 'raft' (I've seen this before).
'c'+'raft'='CRAFT'

Can you help me to learn more?

(Other definitions for craft that I've seen before include "Create" , "Skilled occupation or small boat" , "Art; skilled trade" , "Vessel; skill" , "Art; ship" .)

I've seen this clue in The Independent.
