Question 48 ONC06 - Master LT 100 GRT

The Correct Answer is C **Why Option C is Correct:** Option C, "One prolonged and two short blasts at two-minute intervals," is the correct fog signal specified by the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 35(c), which applies to both international (high seas) and inland waters (where COLREGs are in force or adopted). Rule 35(c) states that a vessel **not under command**, a **vessel restricted in her ability to maneuver** (which a vessel engaged in fishing while at anchor is considered to be, as she is constrained by her fishing gear and anchorage), a **vessel constrained by her draft**, a **sailing vessel**, a **vessel engaged in fishing, or a vessel engaged in towing or pushing** shall sound, at intervals of not more than two minutes, **one prolonged blast followed by two short blasts** (— • •). **Why the Other Options are Incorrect:** * **A) A rapid ringing of the bell for five seconds at one-minute intervals:** This signal is designated for a vessel **at anchor** (Rule 35(g)). While the fishing vessel is at anchor, because she is also engaged in fishing (and thus restricted in her maneuverability), she must use the signal appropriate for her restricted status, which overrides the simple "vessel at anchor" signal. * **B) One prolonged and three short blasts at two-minute intervals:** This signal is designated for a **towed vessel** or the last vessel of a tow where manned (Rule 35(e)). It is not the signal for a vessel engaged in fishing. * **D) A sounding of the bell and gong at one-minute intervals:** This signal (rapid ringing of the bell for 5 seconds and, immediately after, the sounding of the gong rapidly for 5 seconds) is designated for a **vessel aground** (Rule 35(h)). It is not the signal for a vessel engaged in fishing while at anchor.
