When proceeding along a narrow channel or fairway on a power-driven vessel, who should not impede your passage?

The correct response highlights the importance of understanding the navigation rules that apply in confined waters. When navigating through a narrow channel or fairway, vessels that are restricted in their ability to maneuver, such as those engaged in underwater operations, are granted the right of way to ensure their safe passage. This is because these vessels have limitations due to their operational requirements, which can hinder their ability to change course or speed quickly.

In a narrow channel, the rules prioritize the safety and maneuverability of vessels that have restrictions. By recognizing that vessels restricted in their ability to maneuver should not be impeded, operators can ensure compliance with the COLREGs and enhance safety for all users navigating the channel. Other types of vessels, such as smaller boats, fishing vessels, or even larger vessels, may not have the same restrictions and thus may be more flexible in their movement, meaning that they can generally take action to avoid impeding the passage of a power-driven vessel navigating safely through the channel.
