Craft or container (6)
I believe the answer is:
vessel
This clue is a double definition.
'craft' is the first definition.
(I know that craft can be written as vessel)
'container' is the second definition.
(I know that vessel is a type of container)
(Other definitions for vessel that I've seen before include "one swimming in blood?" , "Container for liquid or craft for water" , "A ship or kitchen utensil" , "Ship, or artery" , "Large boat; container" .)
