U.S. Coast Guard Requirements for National OUPV or Master up to 100 Tons

A Captain’s License is required to operate a commercial vessel or to take paying passengers out on your vessel. Understanding the Captain’s License Requirements is important prior to taking a captain’s license course. The prerequisites should be reviewed before applying for any U.S. Coast Guard credential. This is advised so you don’t spend your time and money pursuing a license that you don’t qualify for. For helpful credential information and application packets, and official forms click here.
