Cruiser possibly finds love in club (4)
I believe the answer is:
boat
'cruiser possibly' is the definition.
(cruiser is a kind of boat)
'love in club' is the wordplay.
'love' becomes 'o' (In tennis, 'love' means 'zero').
'in' is an insertion indicator.
'club' becomes 'bat' (bat is a kind of club**).
'o' going into 'bat' is 'BOAT'.
'finds' is the link.
(Other definitions for boat that I've seen before include "Contest on the Thames" , "Vehicle for travelling over water" , "Vessel for travelling on water" , "See 18" , "See 12 Down" .)
