I will pay any price, let me run the ship!!!

It's a long arduous process. Schooling and serving on board other vessels as well as serving time in other capacities on a cruise ship are required. Even to become a master on a freighter takes a long time. Good luck to you!

First, enroll at one of the seven maritime academies in America, and get your degree.
