The sound signal that you should hear when a power boat is in the fog is one prolonged blast at intervals of no more than 2 minutes.
A Fog Horn.
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.

No. They have long O sounds. You can hear the letter O (oh) in both of them. In boat, it is the OA combination.
The sound signals that it is a sailing vessel underway when you hear one prolonged blast plus two short blasts every two minutes.

I live on a lake and swim quite often. When you go underwater and a boat goes by a 1/4 mile away, you can distinctly hear the prop and engine whirring. Also, the boat sounds much closer and louder than it does above water because sound travels better in water than in air. This is because it is more dense than air.
