Question 1 GLI01 - Master-Unlimited Tonnage

The Correct Answer is B **Explanation for Option B ("Vessel constrained by her draft"):** Option B is correct because the term "vessel constrained by her draft" is **NOT** defined or used in the Inland Navigation Rules (33 U.S.C. § 2000 et seq.). This designation and its associated maneuvering rules are reserved exclusively for the International Rules (COLREGs Rule 3(j) and Rule 28) for vessels operating on the high seas. The Inland Rules recognize that water depth is a factor in domestic waters but do not grant special maneuvering status based solely on draft. **Explanation for the other options (Why they are incorrect):** * **A) Seaplane:** This term is defined in the Inland Rules. Inland Rule 3 (General Definitions) states that the definition of a "Vessel" includes "seaplanes used as water craft." * **C) Restricted visibility:** This term is explicitly defined in the Inland Rules. Inland Rule 3 defines "Restricted visibility" as "any condition in which visibility is restricted by fog, mist, falling snow, heavy rainstorms, sandstorms, or any other similar causes." * **D) Underway:** This term is explicitly defined in the Inland Rules. Inland Rule 3 defines "Underway" as "a vessel that is not at anchor, made fast to the shore, or aground."
