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.
Does this include Inland and the Great Lakes?
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.
What are the limitations on Western Rivers?
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.
