Arrange chores on a ship (8)
I believe the answer is:
schooner
'a ship' is the definition.
(I know that schooner is a type of sail ship)
'arrange chores on' is the wordplay.
'arrange' is an anagram indicator.
'chores'+'on'='choreson'
'choreson' anagrammed gives 'SCHOONER'.
(Other definitions for schooner that I've seen before include "Swift sailing vessel - sherry glass" , "9 [CONTAINER" , "Item used for drinking" , "No chores on this sailing ship" , "Two-master; a glass" .)
