On board a cabin cruiser, each passenger heads to topside (10)
I believe the answer is:
acceptable
'to topside' is the definition.
I can't judge whether this defines the answer.
'on board a cabin cruiser each passenger heads' is the wordplay.
'on' is a charade indicator (letters next to each other).
'board' becomes 'table' (both can mean food).
'heads' indicates taking the first letters.
The initial letters of 'cabin cruiser each passenger' is 'ccep'.
'a'+'ccep'='accep'
'table' put after 'accep' is 'ACCEPTABLE'.
Can you help me to learn more?
(Other definitions for acceptable that I've seen before include "Satisfactory, adequate" , "Of (marginally) satisfactory quality" .)
