My cat has unusual name: “Chichester”? (9)

Ross

I believe the answer is:

yachtsman

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

'chichester?' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see an association between them that I can't see?

'my cat has unusual name' is the wordplay.
'unusual' indicates an anagram.
'name' becomes 'n' (common abbreviation e.g. on forms).
'my'+'cat'+'has'='mycathas'
'mycathas' is an anagram of 'yachtsma'.
'yachtsma'+'n'='YACHTSMAN'

Can you help me to learn more?
