Question 31 GLI05 - Master or Mate of LT 200 GRT

The Correct Answer is C A vessel displaying the shape shown in illustration D010RR (a black diamond shape) is indicating that it has a tow that exceeds 200 meters in length. According to the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 24 (Towing and Pushing), a vessel engaged in towing where the length of the tow from the stern of the towing vessel to the after end of the tow exceeds 200 meters must exhibit a diamond shape where it can best be seen. This shape is used both internationally and in inland waters (where similar rules are often adopted). **Why the other options are incorrect:** * **A) Is at anchor:** A vessel at anchor displays one black ball (or two black balls if exceeding 50 meters in length), not a diamond shape. * **B) Is not under command:** A vessel not under command displays two black balls in a vertical line, not a diamond shape. * **D) Has a tow that is carrying hazardous cargo:** While vessels carrying hazardous cargo may have specific marks required by local or international regulations (such as specific flags or placards), the diamond shape specifically signifies the length of the tow, not the nature of the cargo being towed.
