Connecticut Safe Boating Practice Test

What sound signal indicates that a vessel is operating under astern propulsion?

1. One prolonged blast

2. One short blast

3. Three short blasts

4. Two short blasts

The correct answer is: Three short blasts

The sound signal indicating that a vessel is operating under astern propulsion is three short blasts. This specific signal communicates to other vessels that the boat is in reverse and helps ensure safe navigation in shared waterways. Sound signals are crucial for maintaining awareness of vessel movements, especially in situations where visibility might be limited, such as foggy conditions or at night. By following these signaling conventions, mariners convey their intentions clearly, enabling them to avoid collisions and navigate safely. Understanding and using the correct sound signals is a key aspect of effective boating safety practices.
