Wave going right through vessel (7)
I believe the answer is:
breaker
'wave' is the definition.
(I know that breaker is a type of wave)
'going right through vessel' is the wordplay.
I cannot quite see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is present in the answer.
'vessel' could be 'beaker' (beaker is a kind of vessel) and 'beaker' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for breaker that I've seen before include "Someone broadcasting on Citizen's Band radio" , "one stopping, might you say?" , "from rider disciplining horse?" , "White-topped wave" , "Roller?" .)
