Ships string bean I ordered (11)

I believe the answer is:

brigantines

I'm a little stuck... Click here to teach me more about this clue!

'ships' is the definition.
The answer and definition can be both man-made objects as well as being plural nouns.
Perhaps there's an association between them I don't understand?

'string bean i ordered' is the wordplay.
'ordered' indicates an anagram.
'string'+'bean'+'i'='stringbeani'
'stringbeani' is an anagram of 'BRIGANTINES'.

Can you help me to learn more?
