In theory yes and the boat would also have to be licensed and meet all safety regulations.
The captain's license states that it must be carried at all times while underway. I left mine at home once while moving the boat from one dock to another. They let me go home to get the license and the proceeded to provide me with a $1000 fine anyway. I just stuck out my wrists and told them to take me off to jail right now as there was no way I was going to pay it. It took them a second to realize I was serious and they let me off.
