I want to know the answer to the following question:
What maritime advantage did the Kalingans have?
All the background I'm provided with is that "Kaḷingan military might was reinstated by Khārabēḷa: under Khārabēḷa's generalship, the Kaḷinga state had a formidable maritime reach with trade routes linking it to the then-Simhala (Sri Lanka), Burma (Myanmar), Siam (Thailand), Vietnam, Kamboja (Cambodia), Malaysia, Borneo, Bali, Samudra (Sumatra) and Jabadwipa (Java).". Is that enough to answer the question?
Answer: yes
