MMC endorsement for service as master or mate on ocean waters qualifies the mariner to serve in the same grade on any waters, except towing vessels upon western rivers subject to the limitations of the endorsement.
Yes. Any license or MMC endorsement issued for service as master or mate on near-coastal waters qualifies the mariner to serve in the same grade on Great Lakes and inland waters, except towing vessels upon western rivers subject to the limitations of the endorsement.
Before serving as a master or mate (pilot) of towing vessels on the Western Rivers, mariners must possess 90 days of observation and training and have their MMC include an endorsement for Western Rivers.
