Question 1

The Correct Answer is B **Explanation of Option B (Vessel constrained by her draft):** The term **“vessel constrained by her draft”** is defined in **Rule 3(l)** of the International Regulations for Preventing Collisions at Sea (COLREGs). This definition is specifically **omitted** from the Inland Navigation Rules. Therefore, the term is not defined for vessels operating solely under Inland Rules jurisdiction. *** **Explanation of the Other Options (Why they are incorrect):** * **A) Seaplane:** This term is defined in Inland Rule 3(j) (and COLREG Rule 3(j)). * **C) Restricted visibility:** This term is defined in Inland Rule 3(k) (and COLREG Rule 3(k)). * **D) Underway:** This term is defined in Inland Rule 3(b) (and COLREG Rule 3(b)).
