Question 36 TV02 - Towing Vessels - Great Lakes and Inland

The Correct Answer is A ### Explanation of Correct Option (A) **A) one short blast** is the correct signal. According to the U.S. Inland Navigation Rules (Rule 34(c) - signals when overtaking), when a vessel being overtaken agrees to the overtaking vessel's proposal (in this case, passing on the starboard side, signaled by one short blast from the overtaking vessel), the vessel being overtaken must sound a signal of agreement. The agreed-upon signal for assent (agreement) to an overtaking maneuver in inland waters is **one short blast**. ### Explanation of Incorrect Options **B) one prolonged, one short, one prolonged, and one short blast in that order:** This is the Restricted Visibility signal used by a vessel at anchor (Rule 35(f)). It has no application to maneuvering signals like agreeing to be overtaken. **C) two prolonged blasts:** There is no standard maneuvering or warning signal defined by the Rules that consists solely of two prolonged blasts. (Note: A prolonged blast is defined as 4 to 6 seconds; two short blasts is used for passing starboard to starboard, but two *prolonged* blasts is not a standard response for assent.) **D) two prolonged followed by two short blasts:** This signal is defined as the "general alarm signal" used to summon the crew to their stations, often in case of fire or emergency (not related to maneuvering).
