One hurried to go up on board ship for drinks (8)
I believe the answer is:
sidecars
'drinks' is the definition.
(sidecar is a kind of drink)
'one hurried to go up on board ship' is the wordplay.
'one' becomes 'i' (Roman numeral).
'hurried' becomes 'raced' ('race' can be a synonym of 'hurry').
'to go up' shows that the letters should be reversed in order (I've seen 'goes up' mean this).
'on board' indicates putting letters inside.
'ship' becomes 'ss'.
'raced' written backwards gives 'decar'.
'i'+'decar'='idecar'
'idecar' going within 'ss' is 'SIDECARS'.
'for' acts as a link.
(Other definitions for sidecars that I've seen before include "cocktails" , "They're attached to motorbikes to carry passengers" .)
