In restricted visibility, a power-driven vessel must navigate with caution and take specific measures to ensure safety. It is required to sound the appropriate signals, such as prolonged blasts on the whistle, to indicate its presence to other vessels. Additionally, the vessel should reduce speed, maintain a proper lookout, and be prepared to take evasive action if necessary. Implementing these precautions helps prevent collisions and ensures safe navigation in challenging conditions.
In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every 2 minutes. This signal indicates the vessel's presence and helps prevent collisions when visibility is limited. The prolonged blast typically lasts about 4 to 6 seconds.

A power-driven vessel underway in restricted visibility is required to sound a prolonged blast on its whistle every two minutes. This signal typically lasts for about four to six seconds. The purpose of this sound is to alert other vessels of its presence in conditions where visibility is limited, ensuring safety on the water.
In restricted visibility, a power-driven vessel under way is required to sound one prolonged blast every 2 minutes. This signal is used to indicate the vessel's position and to alert other vessels in the vicinity. The prolonged blast lasts for about four to six seconds.
A power-driven vessel underway in restricted visibility is required to sound one prolonged blast at intervals of not more than two minutes. This signal indicates the vessel's presence and helps prevent collisions. Additionally, if the vessel is making way through the water, it may also sound two short blasts to indicate its maneuverability.
