Which two types of signals are used in boating emergencies?

The use of sound signals and visual signals in boating emergencies is vital for communication and alerting others to your situation. Sound signals can include horn blasts or whistle sounds that convey a specific message, indicating distress or the need for help. These auditory signals can carry over distances, especially in locations with limited visibility, and can be an effective way to attract attention.

Visual signals, on the other hand, include signals such as flags, lights, or flares that can be seen from a distance. These signals are particularly important during the day or in good visibility to signal your distress to other boaters nearby. The combination of both sound and visual signals enhances the chances of being noticed by other vessels or rescue teams in the event of an emergency, increasing the likelihood of receiving assistance quickly.

The other options, while they may include some elements related to signaling, do not encompass the critical methods commonly recognized for use in emergencies on the water. This understanding is essential for safe navigation and effective communication while boating.
