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.
Rules of the Road Rule 35 Sound Signals in Restricted Visibility/International (a) A power driven vessel making way through the water shall sound at intervals of not more than 2 minutes one prolonged blast.
In restricted visibility, a power-driven vessel underway is required to sound one prolonged blast every 2 minutes. This signal is meant to indicate the vessel's presence to other nearby vessels in low visibility conditions. The prolonged blast lasts for about 4 to 6 seconds. This sound signal helps enhance safety by alerting others to the vessel's location, allowing for better navigation and collision avoidance.
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.
