In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every two minutes. This signal helps communicate the vessel's presence to other nearby vessels, especially when visibility is limited. The prolonged blast lasts for about four to six seconds and is an essential safety measure to prevent collisions.

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.
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 under way is required to emit a sound signal at intervals of not more than two minutes when visibility is restricted. This signal typically consists of one prolonged blast, which alerts other vessels to its presence and intention, as per maritime navigation rules. Such measures are essential for maintaining safety and preventing collisions in low visibility conditions.
