What are Near Coastal waters?

Near-coastal means ocean waters not more than 200 miles offshore from the U.S. and its possessions, except for MMCs endorsed as Operator of Uninspected Passenger Vessel for which near-coastal is limited to waters not more than 100 miles offshore from the U.S. and its possessions.

This means your Master or Mate NC license is valid out to 200 nm; or if you have an OUPV license, it is valid out to 100 nm.

Can I work on inland waters?

Yes. Any license or MMC endorsement issued for service as master, mate or OUPV 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 towing limitations?

Before serving as master or apprentice mate, based on current credentials, of towing vessels on the Western Rivers, mariners must possess 90 days of observation and training and their MMC must include an endorsement for Western Rivers.

Do I have to update my MMC to receive this endorsement?

Yes. You will have to meet the requirements for the towing endorsement for Western Rivers and apply for an Increase in Scope which is also called a Modification.
