46 C.F.R. § 10.430 Licenses for the Great Lakes and inland waters.
Title 46 - Shipping
Any license issued for service on the Great Lakes and inland waters is valid on all of the inland waters of the United States as defined in this part. Any license issued for service on inland waters is valid for the inland waters of the United States, excluding the Great Lakes. Licenses with either a Great Lakes and inland or an inland route are valid for service on the sheltered waters of the Inside Passage between Puget Sound and Cape Spencer, Alaska. As these licenses authorize service on waters seaward of the International Regulations for Preventing Collisions at Sea (COLREGS) demarcation line as defined in 33 CFR part 80, the applicant must complete an examination on the COLREGS or the license must be endorsed with an exclusion from such waters.
