My brig's wrecked in Humber port (7)

I believe the answer is:

grimsby

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

'humber port' is the definition.
The definition suggests a singular noun which matches the answer.

'my brig's wrecked' is the wordplay.
'wrecked' indicates anagramming the letters.
'my'+'brigs'='mybrigs'
'mybrigs' is an anagram of 'GRIMSBY'.

'in' is the link.

Can you help me to learn more?
