Where Marco Polo went abroad in a yacht (6)

Ross

I believe the answer is:

cathay

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

'where marco polo went abroad' is the definition.
The definition suggests a singular noun which matches the answer.

'a yacht' is the wordplay.
'a yacht' anagrams to 'CATHAY'.
Though, I am not clear how the anagram is indicated.

'in' acts as a link.

Can you help me to learn more?

(Other definitions for cathay that I've seen before include "Name for China in medieval Europe" , "China long ago" , "poetic land" , "Literary name for China" , "Old name for China with a feline to start" .)
