Hi,
It depends mostly on the scope of the two courses. After having gone through all the information available on Naval Architecture and Ocean Engineering, what I can say is, the opportunities that are offered after the degree aren't promising enough as compared to EEE. But, there are really good opportunitites abroad so, you can complete 4 years from IIT then go abroad to do PG in the same subject.
If you are not interested in going abroad, I suggest you take up EEE because, here, there is a secure future. But, if you have an interest in the subject and are willing to abroad as well then, Naval Architecture and Ocean Engineering is a good option too.
