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.
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.
One prolonged blast followed two short blasts, every two minutes, not to exceed two minutes. Rule 35-Sound Signals in restricted visibility.

A vessel signals its bearing by the position where the signal flag is hoisted on the ship. For example, if the flag is hoisted on the starboard side, it indicates a bearing to the starboard side of the vessel. In this way, signal flags are used to communicate information about a vessel's orientation and position to other ships.

A vessel at sea is said to be underway.
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.
