Abroad, target a series of boat races (7)
I believe the answer is:
regatta
'series of boat races' is the definition.
(I've seen this before)
'abroad target a' is the wordplay.
'abroad' is an anagram indicator (abroad can mean moving around).
'target' with letters rearranged gives 'regatt'.
'regatt'+'a'='REGATTA'
(Other definitions for regatta that I've seen before include "Number of yachts in sporting event" , "competition between banks" , "E.g. Henley" , "Series of yacht races" , "Rowing or sailing event" .)
