Distress Signals

Mariner distress signals are used to attract the attention of other vessels or rescue crews in the event of an emergency. There are three main types of mariner distress signals:

Visual signals: These signals are visible from a distance and can be seen during the day or night. They include flags, flares, smoke signals, and mirrors.

Audio signals: These signals are audible from a distance and can be heard during the day or night. They include horns, whistles, and air horns.

Radio signals: These signals are transmitted over radio frequencies and can be received by other vessels or rescue crews. They include the international distress signal "Mayday" and the digital selective calling (DSC) system.
Distress signals can help you in a number of ways. They can:

Alert other vessels or rescue crews to your location.
Help to identify your vessel as being in distress.
Provide a visual or audible cue to help rescue crews locate you.
If you are in distress while boating, it is important to use all of the distress signals that you have available to you. This will help to ensure that you are quickly and safely rescued.

Here are some additional tips for using mariner distress signals:

Make sure that you know how to use all of the distress signals that you have on board.

Practice using the distress signals in a safe environment before you need to use them in an emergency.

Keep your distress signals in a visible and accessible location.

Replace your distress signals regularly, especially if they have been exposed to the elements.

By following these tips, you can help to ensure that you are prepared to use mariner distress signals in the event of an emergency.
