B. Two prolonged blasts only
C. Two short blasts followed by two prolonged blasts
D. Two prolonged followed by two short blasts

Answer 1

The correct signal to indicate the intention to overtake another vessel on its port side in a narrow channel is two prolonged blasts followed by two short blasts. The correct option is D. Two prolonged followed by two short blasts

Step-by-step explanation:

When you intend to overtake a vessel in a narrow channel and wish to pass along the vessel's port side, the appropriate signal to make your intentions clear is: two prolonged blasts followed by two short blasts. This signal, according to maritime navigation rules, communicates to the other vessel that you are planning to overtake on their port side.

It is imperative for the safety of both vessels that this signal is made and understood before overtaking in a narrow channel. Maritime safety and signal communication are crucial elements in navigational practices to avoid collisions and accidents on the water.
