There are several sound signals for a vessel underway in restricted visbility.
- A power drivel vessel underway, making way- 1 PROLONGED Blast (4-6 seconds duration) Not to exceed every two minutes.
- A power driven vessel underway NOT making way-2 PROLONGED every 2 minutes, not exceed two minutes.
- A vessel not under command, a vessel restricted in maneuverability, a vessel towing, a vessel engaged in fishing, a sailing vessel & a vessel constrained by her draft (International only) 1 PROLONGED blast followed by two short blast (duration about 1 second per short blast) every two minutes, not to exceed two minutes.
- A MANNED vessel being towed shall sound 1 PROLONGED followed by 3 SHORT blasts every two minute, not to exceed two minutes.
See the link provided for the International and Inland Navigational Rules of the Road. Rule 35.
for power driven vessels over 12meters it's one long blast every 2 minutes

What sound signal indicates that a sailing vessel is underway in the fog?
One prolonged blast followed two short blasts, every two minutes, not to exceed two minutes. Rule 35-Sound Signals in restricted visibility.
What sound signal indicates a sailing vessel is underway in the fog and how frequently?
Rules of the RoadRule 35Sound Signals in Restricted Visibility(C) A vessel not under command, a vessel restricted in her ability to maneuver, a vessel constrained by her draft, a sailing vessel, a vessel engaged in fishing, and a vessel engaged in towing or pushing another vessel shall..........sound at intervals of not more than two minutes, three blast in succession, namely one prolonged followed by two short blasts.
You are out on the water in foggy conditions. You hear one prolonged blast every two minutes. What does this sound signal mean?
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.

What sound signal indicates that a power-driven vessel is underway in the fog?
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.
What sound signal indicated a power driven vessel in underway in the fog?
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.7 blasts
When a Sailboat is underway in the fog what sound signal should you here?
One prolonged blast plus two short blasts every two minutes
A sailboat is underway in the fog. What sound should you hear?
One prolonged blast plus two short blasts every two minutes. Explanation: 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 plus two short blasts at intervals of not more than two minutes is the signal used by sailing vessels.
What sound signal indicates that a sailing vessel is in the fog?
Rule 35 part c of the International Regulations for Preventing Collisions at Sea (72 COLREGS) states that when in restricted visibility (i.e. fog) a sailing vessel is required to sound one prolonged blast followed by two short blasts on the vessel's whistle, at intervals of not more than two minutes. Please refer to the link below.
