She rows a boat from Oman, skirting terrible wars by shore of ocean (9)
I believe the answer is:
oarswoman
'she rows a boat' is the definition.
I can't tell whether this defines the answer.
'oman skirting terrible wars by shore of ocean' is the wordplay.
'skirting' is an insertion indicator.
'terrible' indicates anagramming the letters.
'by shore of ocean' becomes 'o' (I can't justify this - if you can you should give a lot more credence to this answer).
'wars' anagrammed gives 'arsw'.
'arsw'+'o'='arswo'
'oman' placed around 'arswo' is 'OARSWOMAN'.
'from' acts as a link.
Can you help me to learn more?
(Other definitions for oarswoman that I've seen before include "Girl having paddle" , "Rower" , "River user" .)
