Boat sure to be wrecked — by me? (8)

I believe the answer is:
saboteur
'me?' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see an association between them that I don't see?
'boat sure to be wrecked' is the wordplay.
'to be wrecked' indicates anagramming the letters.
'boat'+'sure'='boatsure'
'boatsure' anagrammed gives 'SABOTEUR'.
'by' is the link.
Can you help me to learn more?
(Other definitions for saboteur that I've seen before include "One causes damage to subvert" , "Political wrecker" , "Rebel" , "One causing deliberate destruction" , "Abuser to become a kind of destroyer" .)
