Question 16 RVR02 - Master of LT 500-1600 GRT

The Correct Answer is B **Explanation for Option B (The Mississippi River System) being correct:** The Inland Navigation Rules (33 CFR Subchapter E, specifically Rule 3 - General Definitions) apply to designated waters. These "Inland Waters" are defined areas shoreward of the demarcation lines separating them from the International Waters (COLREGs applicability). The Mississippi River System, including the Western Rivers (as defined in 33 CFR 89.25), the Mississippi River itself, and its major tributaries, is clearly designated as U.S. Inland Waters for the purpose of the Inland Navigation Rules. **Explanation of why other options are incorrect:** * **A) The Great Lakes in their entirety:** While the Inland Rules apply to specific areas of the Great Lakes (i.e., waters shoreward of the established demarcation lines), the Great Lakes in their *entirety* are subject to special rules (the Great Lakes Rules, often treated as a subset or integration of Inland Rules) and include areas that are international boundaries, making the blanket statement inaccurate for the sole purpose of defining "Inland Waters" under the rules set. * **C) U.S. waters out to three miles offshore:** This area (the territorial sea) is explicitly defined as international waters (or seaward of the demarcation lines), and the International Rules (COLREGs) apply there, not the Inland Rules. Inland Waters are generally shoreward of the COLREG Demarcation Lines. * **D) The St. Lawrence River to Anticosti Island:** The demarcation lines for the St. Lawrence River are located much further upstream, near St. Regis, Quebec/Cornwall, Ontario. Seaward of this point, including the entire stretch down to Anticosti Island, the International Rules (COLREGs) apply.
