Glared at the boat that was in front (7)
I believe the answer is:
scowled
'glared' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps you can see an association between them that I don't see?
'at the boat that was in front' is the wordplay.
'at' means one lot of letters go next to another.
'the boat' becomes 'scow' (scow is a kind of boat).
'that was in front' becomes 'led' (I've seen this in another clue).
'scow' put next to 'led' is 'SCOWLED'.
Can you help me to learn more?
(Other definitions for scowled that I've seen before include "Looked gloomy" , "Pulled a face" .)
