Final answer:
In a narrow channel, the person or vessel that has the right of way is known as the privileged vessel, while the others must give way and not impede safe passage.
Step-by-step explanation:
In a narrow channel, the person or vessel that has the right of way is known as the privileged vessel. According to maritime laws and regulations, the privileged vessel has the right to proceed without being impeded by other vessels. The person or vessel that does not have the right of way and must give way to the privileged vessel is known as the stand-on vessel.
For example, if a large ship is navigating a narrow channel, smaller boats or vessels must yield and give way to the larger ship to ensure safe passage. By doing so, the smaller boats prevent any potential accidents or hindrances to the safe navigation of the wider vessel.
Therefore, the answer to your question is that anyone who is not the privileged vessel shall not impede safe passage in a narrow channel.
