Question 1 GLI06 - Master or Mate of LT 100 GRT

The Correct Answer is B **Explanation for Option B (Correct Answer):** The term "vessel constrained by her draft" is a status definition found exclusively in **Rule 3(l)** of the **International Regulations for Preventing Collisions at Sea (COLREGs/72)**, which apply on international waters. This term is **not** defined in **Rule 3 (General Definitions)** of the **Inland Navigation Rules** (33 CFR Part 83), nor is it used anywhere else in the Inland Rules. Inland waters generally lack the need for this specific status because of shallower depths and differing traffic patterns, and the "vessel restricted in her ability to maneuver" status (Rule 3(g) and Rule 18(a)(ii)) is sufficient to cover large vessels moving in channels. **Explanation for Other Options (Incorrect Answers):** * **A) Seaplane:** This term **is** defined in the Inland Navigation Rules, specifically in **Rule 3(n)** (General Definitions). * **C) Restricted visibility:** This term **is** defined in the Inland Navigation Rules, specifically in **Rule 3(l)** (General Definitions). * **D) Underway:** This term **is** defined in the Inland Navigation Rules, specifically in **Rule 3(j)** (General Definitions).
