Something afoot - e.g., wrecking boats (5)
I believe the answer is:
sabot
'something afoot e g' is the definition.
I can't judge whether this defines the answer.
'wrecking boats' is the wordplay.
'wrecking' indicates anagramming the letters (I've seen this in other clues).
'boats' anagrammed gives 'SABOT'.
Can you help me to learn more?
(Other definitions for sabot that I've seen before include "Boast about wooden shoe" , "Wooden-soled 13 down" , "French wooden shoe" , "what's afoot?" , "Wooden clog" .)
