Designer or Architect?

[Yachts CF]

Hello, I have a question about what I should study. I am currently a High School Senior from Miami. I was going to go to the Art Institute of Ft. Lauderdale to study Yacht and Marine Design, but unfortunately it is too expensive and they only offered a BA. degree and my aspirations are higher. Instead I applied at FIU's Architecture school. I would like to design megayachts for european yards and cruise ships but I don't know if I am in the right path. Naval Architecture isn't for me since I want to design, like what Tim Heywood does. I am creative and very innovative, I've been designing since I was a kid. If anyone has any suggestions please let me know. Thanks.
