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 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.

One long two shorts is a sound signal made in restricted visibility by the following classes of vessels:Not Under CommandRestricted ability to manoeuvreConstrained by draughtSailing vesselVessel engaged in fishingVessel engaged in towing or pushingA vessel engaged in fishing would make this signal at anchor and underway.All other classes of vessel listed would make the signal only when underway.
