BOTH INTERNATIONAL & INLAND You are in charge of a 120 meter power-driven vessel at anchor in fog, sounding the required anchor signals. You hear the fog signal of a vessel underway off your port bow. Which signal may you sound to give warning of your position?
• Rule 35 – Sound Signals in Restricted Visibility (vessels underway vs. vessels at anchor) • Difference between required anchor signals and optional warning signals • Meaning of maneuvering and warning signals in open water (Rule 34) vs. fog signals (Rule 35)
• First, decide which rule applies here: are you using maneuvering signals or restricted-visibility/anchor signals? • Look at each choice: which patterns are normally used to indicate course/engine actions, and which one is specifically tied to a vessel at anchor in fog? • Ask yourself: is the question asking for a danger/maneuvering signal, or a special signal allowed to an anchored vessel to indicate its position to another ship in fog?
• Verify in Rule 35 what sound signals a vessel at anchor must make, and which additional signal it may make to warn of its position. • Check in Rule 34 which blast patterns mean “altering course to port,” “operating astern propulsion,” and “danger signal.” • Confirm which option is not a standard maneuvering or danger signal under Rule 34, but instead matches the optional warning for a vessel at anchor in fog.
