The Coast Guard will no longer enforce mask requirements in outdoor areas of maritime transportation conveyances and hubs.
The Coast Guard continues to work closely with the CDC for maritime related issues and confirmed with the CDC that the CDC requirements in Marine Safety Information Bulletin
(MISB) 02-21 Change 1 remains the most current guidance.
On February 1, 2021, the Coast Guard issued Marine Safety Information Bulletin (MSIB) 02-21, COVID-19 Safety Requirements in the Marine Transportation System. Since the release of the MSIB, the Coast Guard received numerous questions regarding the applicability of the mask mandate.
The Coast Guard Assistant Commandant for Prevention Policy has published Marine Safety Information Bulletin 02-21 “COVID-19 Safety Requirements in the Maritime Transportation System” to provide information related to the requirement of all persons traveling on all commercial vessels to wear a mask.
