Question 1 GLI02 - Mate of Unlimited Tonnage

The Correct Answer is B **Explanation for Option B (Vessel constrained by her draft):** Option B, "Vessel constrained by her draft," is the correct answer because this term is **not** defined in the Inland Navigation Rules (33 CFR Subchapter E, Part 83). The concept of a vessel constrained by her draft, and the associated signal lights and shapes, is exclusive to the International Regulations for Preventing Collisions at Sea (COLREGs), specifically Rule 3(l). Because inland waters generally do not have the same extreme depth limitations or the same unrestricted maneuvering expectations as deep international waters, this designation is omitted from the Inland Rules. *** **Explanation for Other Options (Why they are incorrect):** * **A) Seaplane:** This term **is** defined in the Inland Rules (33 CFR § 83.03(e)). * **C) Restricted visibility:** This term **is** defined in the Inland Rules (33 CFR § 83.03(k)), typically covering any condition in which visibility is impaired (such as fog, mist, falling snow, heavy rainstorms, sandstorms, or any other similar causes). * **D) Underway:** This essential term, meaning a vessel that is neither at anchor, nor made fast to the shore, nor aground, **is** defined in the Inland Rules (33 CFR § 83.03(i)).
