Yacht is at sea in old Black Sea region (7)

Ross

I believe the answer is:

scythia

'old black sea region' is the definition.
(I've seen this before)

'yacht is at sea' is the wordplay.
'at sea' is an anagram indicator.
'yacht'+'is'='yachtis'
'yachtis' with letters rearranged gives 'SCYTHIA'.

'in' acts as a link.

(Other definitions for scythia that I've seen before include "Ancient region of SE Europe and Asia" , "old Black Sea region" .)

I've seen this clue in The Independent.
