A power driven vessel making way shall sound at intervals of not more than 2 min one prolonged blast. A power driven vessel under way, but stopped & no making way, shall sound at intervals of not more than 2 min two prolonged blas in sucession, at intervals of about 2 sec between them.
One prolonged blast
One prolonged blast
A power-driven vessel under way sounds one prolonged blast not less than every two minutes. However if it is less than 12meters in length it is not required to give any signal.
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 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 underway is required to sound one prolonged blast followed by two short blasts every two minutes. This signal indicates the vessel's presence and helps to communicate its intention to other vessels in the vicinity. The prolonged blast lasts for about four to six seconds, while each short blast lasts for about one second.
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.
I am a power-driven vessel underway. Sound signals let other boaters know where you are located during periods of restricted visibility, such as extreme fog. If you hear the fog signal of a vessel you cannot see, slow to a minimum speed until you are sure there is not a risk of collision. One prolonged blast at intervals of not more than two minutes is the signal used by power-driven vessels when underway.

A vessel that is underway but not making way would exhibit sidelights if it is a power-driven vessel or a sailing vessel with a motor. Sidelights consist of a green light on the starboard side and a red light on the port side, indicating the vessel's orientation. Even when not making way, the sidelights serve to signal the vessel's presence and direction to other vessels in the vicinity. Additionally, a vessel at anchor would display an all-round white light instead of sidelights.
None. A vessel underway under normal conditions does not need to make any sound signal.If the vessel ceases to make way it still does not make a sound signal unless special circumstances apply.
A vessel that sounds the same fog signal whether underway or at anchor is a sailing vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGs), a sailing vessel under sail alone is required to sound one prolonged blast followed by two short blasts. This signal is used to indicate its presence and position in reduced visibility conditions, regardless of its status.
