Question 1 GLI07 - OUPV

The Correct Answer is B **Explanation for Option B ("Vessel constrained by her draft"):** The term "vessel constrained by her draft" is **NOT** defined in the Inland Navigation Rules (33 U.S.C. Chapter 83, Rule 3 - General Definitions). This definition is specific to the **International** (COLREGs) Rules (International Rule 3(h)) and applies primarily to vessels navigating international waters that cannot deviate from a course due to the limited depth of water. Since most vessels navigating U.S. inland waters are constrained by fixed channels and depths, the definition was deemed unnecessary and was intentionally omitted from the Inland Rules. **Explanation for Other Options (Why they are incorrect):** * **A) Seaplane:** This term is defined in Inland Rule 3(i): "The term 'seaplane' includes any aircraft designed to maneuver on the water." * **C) Restricted visibility:** This term is defined in Inland Rule 3(l): "The term 'restricted visibility' means 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 defined in Inland Rule 3(j): "The term 'underway' means that a vessel is not at anchor, made fast to the shore, or aground."
