Tuba got transported by craft (7)
I believe the answer is:
tugboat
'craft' is the definition.
(tugboat is a kind of craft)
'tuba got transported' is the wordplay.
'transported' indicates anagramming the letters.
'tuba'+'got'='tubagot'
'tubagot' is an anagram of 'TUGBOAT'.
'by' acts as a link.
(Other definitions for tugboat that I've seen before include "Drawing craft" , "Ship pulling a larger one" , "Powerful vessel used to pull larger ones" , "Harbour craft" , "Vessel towing larger vessels" .)
