College Boat Donation

I’m really considering going to the US Merchant Marine Academy for college. The thing is, I’m not sure if I want to make sailing my life style. Before considering MMA I was thinking about getting a Business Administration degree at a normal college, but the closest thing to a Business Administration degree offered at MMA would be a major in Marine Transportation. Can I get a business oriented job with that degree? I’m assuming I’d need to go to masters school and get a MBA.
