Vessels capsized by a terrible gust? (4)
I believe the answer is:
tugs
'vessels' is the definition.
(tug is a kind of vessel)
'capsized by a terrible gust?' is the wordplay.
'gust' anagrams to 'TUGS'.
Though, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for tugs that I've seen before include "Tows" , "Yanks" , "Pulls hard" , "Pulls in a jerking manner" .)
