Question 43 RVR02 - Master of LT 500-1600 GRT

The Correct Answer is B **Explanation of Correct Option (B):** The question specifies the **INLAND ONLY** rules. Under the U.S. Inland Navigational Rules (Rule 34(a)(i)), when power-driven vessels are meeting, crossing, or overtaking and will pass within 1/2 mile of each other, sound signals are used to indicate *intentions* regarding the passing side. * **One short blast** means: "I intend to leave you on my port side." * **Two short blasts** means: "I intend to leave you on my starboard side." Therefore, two short blasts from either vessel clearly indicates the intention to pass the other vessel such that the other vessel will be on the signaling vessel's **starboard side**. **Explanation of Incorrect Options:** * **A) "I am altering my course to port."** This is incorrect. While altering course to port might accompany a signal, the signal itself (two short blasts) communicates the *passing intention* (leaving the other vessel on the starboard side) under Inland Rules, not just a simple course change. Under International Rules (COLREGs), two short blasts means "I am altering my course to port," but the question specifically requires **INLAND ONLY** answers. * **C) "I intend to leave you on my port side."** This is incorrect. The signal for intending to leave the other vessel on the signaling vessel's port side is **one short blast** under Inland Rules. * **D) "I am altering my course to starboard."** This is incorrect. The meaning of "I am altering my course to starboard" is **one short blast** under International Rules (COLREGs). Under Inland Rules, one short blast indicates the intention to leave the other vessel on the signaling vessel's port side. Two short blasts never means altering course to starboard in either system.
