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.
