Drink with sailors in small club (11)
I believe the answer is:
screwdriver
'drink' is the definition.
(screwdriver is a kind of drink)
'sailors in small club' is the wordplay.
'sailors' becomes 'crew' (I've seen this before).
'in' means one lot of letters goes inside another.
'small' becomes 's' (abbreviation - e.g. clothes size).
'club' becomes 'driver' (driver is a kind of club**).
's'+'driver'='sdriver'
'crew' put inside 'sdriver' is 'SCREWDRIVER'.
'with' acts as a link.
(Other definitions for screwdriver that I've seen before include "it gives the fixer a turn" , "Common tool" , "Cocktail of vodka and orange juice" , "that'll turn a few heads" , "Hand tool - cocktail" .)
