# Coast Guard's Navita platform is now primary for mariner credential applications

Navita became the primary system for Merchant Mariner Credential and medical certificate applications on Sept. 14, weeks after the service authorized 120-day sailing for mariners with expired credentials.

The U.S. Coast Guard launched Navita on Monday, Sept. 14, at 8 a.m. Eastern, making it the primary electronic system for submitting Merchant Mariner Credential and medical certificate applications.[^1]

The launch came weeks after the Coast Guard introduced a temporary relief measure in August that lets eligible mariners with expired Merchant Mariner Credentials keep sailing under a 120-day authorization while the National Maritime Center processes their renewals.[^2]

The credentialing work sits against the crewing rule at the root of American domestic shipping. The Merchant Marine Act of 1936 required a U.S. merchant marine built in U.S. yards and crewed by citizens.[^4] Operating vessels under U.S. laws with U.S. crews carries a cost premium compared with third-world crews, a study of the maritime industry in Puerto Rico found.[^7]

8. Unrestricted competition from foreign-flag vessels could lead to the disappearance of most U.S.-flag vessels in the Puerto Rico trade, but foreign carriers would lose their labor cost advantage if they must comply with U.S. labor rules.
