How to Signal for Help Without a VHF Radio During Boating Emergencies

A flare exploding on air.

Being stranded on the water without a VHF radio can be a frightening experience. However, even without this primary communication tool, there are effective ways to signal for help and increase your chances of a swift rescue. We will tell you all the essential strategies and techniques for attracting attention and getting help when a VHF radio isn't available.

Prepare All Safety Kit That You’ll Need

While a VHF radio is highly recommended, here are some essential safety items to have onboard your Stacer Sea Runner or Stacer Wildrider, if a VHF radio is unavailable:

Visual Distress Signals: Carry a variety of visual distress signals that are readily visible from a distance. This includes orange flares (parachute or handheld), a large orange distress flag, a signal mirror and white handheld flares with powerful flashlights for nighttime signals.

Sound Signals: A loud whistle or air horn can be used to attract attention, especially in calm conditions.

Personal Locator Beam: Consider investing in a PLB, a handheld device that transmits a distress signal directly to search and rescue satellites. However, PLBs can be expensive and may not be an option for everyone.

How to Send A Distress Signal At Daytime

During daylight hours, prioritize attracting visual attention:

Distress Flag: Fly the international distress flag, a large orange flag with a black square above a black circle in the centre, from the highest point on your boat. If you don't have a pre-made flag, create a large orange flag using any available material like a towel or bedsheet.

Signal Mirror: A signal mirror can reflect sunlight over long distances, potentially catching the eye of rescuers. Practice using the mirror beforehand to ensure you can aim the reflected beam effectively.

Smoke Signals: If conditions are suitable (calm winds, no nearby flammable materials), creating controlled smoke signals with damp vegetation or flares can attract attention. Use caution and prioritize safety when using any form of fire.

How to Send A Distress Signal At Nighttime

At night, attracting attention requires different strategies:

Flares: Use handheld or parachute flares according to the manufacturer's instructions. Light a single flare at a time and point it upwards for maximum visibility. Never aim or point a flare at another vessel.

Flashlight: A powerful flashlight can be used to signal for help in Morse code. Learn the international Morse code distress signal (SOS - three short bursts, three long bursts, three short bursts) and practice signalling with your flashlight before encountering an emergency.

Sound Signals: Making Yourself Heard

In calm conditions, sound can be an effective way to attract attention:

Whistle or Air Horn: Repeatedly blow a loud whistle or air horn in short bursts to create a distinctive distress signal.

Strategies for Increasing Visibility

Deploy Your Anchor: Anchoring your boat prevents drifting and makes it easier for rescuers to locate you.

Life Jackets: Ensure everyone onboard wears a life jacket. In an emergency, life jackets not only provide buoyancy but can also improve visibility in the water.

Reflectors: If available, display any reflective surfaces you have onboard, such as life jackets with reflective tape, to increase your visibility at night.

Other Emergency Communication Strategies

Cellular Phone: If you have a cellular phone with a signal, attempt to call emergency services and explain your situation.

Satellite Phone: For those with satellite phones, contact emergency services directly using the satellite network.

If you find yourself in a situation where you need to signal for help without a VHF radio, the most important thing is to stay calm and take action. By utilizing visual and auditory distress signals and following the strategies outlined above, you can significantly increase your chances of being rescued.
