Where a tow exceeds 200m in length, what shapes would be exhibited?

When a tow exceeds 200 meters in length, the appropriate day shapes to exhibit are three shapes that are vertically aligned. This visibility is crucial for ensuring that vessels in proximity are aware of the towing operation and its dimensions.

The use of three shapes, arranged vertically, indicates that the vessel is towing a length of more than 200 meters. This practice is prescribed by the International Regulations for Preventing Collisions at Sea (COLREGs), which aim to promote safety and awareness on the water. The shapes used serve as visual signals to other vessels, thereby facilitating safe navigation and minimizing the risk of collisions.

In contrast, the other options do not adhere to the guidelines stipulated for towing operations of this length, and thus would not convey the necessary information to other mariners effectively.
