In most cases the boat license course can be completed online, and is followed by a boat license test that is also completed online. The boating safety certificate courses are not as comprehensive as those for an automobile driver's license; there's usually no on-water driver's education required, for example.
I’m not sure how you can get so to say “boat driving license” in Saudi Arabia, but in USA we follow these steps: 1. Attend a Maritime High School 2. Get you Bachelor’s Degree 3. Get some experience by working as a deckhand 4. After some years get the following credentials: Merchant Marine Credential and Transportation Worker Identification Credential
5. Become a deck officer(captain)
I don’t think the process to acquire driving license for boat in Saudi differs much from USA. I’d like to add that the process of getting the license isn’t an easy one and requires minimum 5 years of studying. It took me around 7 years studying and working in the same time to be able to lead Naples private boat tours individually.
