U.S. Coast Guard Able Seaman Credential Requirements

U.S. Coast Guard Requirements for Able Seaman Rating

Able Seaman (AB) is a deck rating that requires qualifying experience, exams, and approved training. A mariner that holds an AB endorsement is below Officer and above Ordinary Seaman. The level of AB you qualify for depends on your sea service experience: the amount of days you have documented, the size of the vessels, and the waters operated on.

National Able Seaman is a national (U.S. WATERS) rating. If you plan to use your AB credential in INTERNATIONAL waters, there are additional endorsements you will need and requirements to meet.

Prerequisites must 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.
