Yacht Safety Protocols: An In-Depth Look at Visual Distress Signals

There has never been a point in history when it was safer to take to the world’s great open waters onboard vessels of all kinds. Although many people still lose their lives at sea every year, increased knowledge, general standards of safety, and technological advancements in equipment and weather reporting have made it a much safer endeavour. However, there can never be absolute safety assurance when you set forth on the ocean waves. Accidents and disasters are rare, but they do happen. This article examines how vessels can maximise any trip’s safety and alert others to their distress if necessary. From legally required safety equipment and features on board to recommended signal devices and general best practices. 

 

DISTRESS SIGNALS

The purpose of distress signals is to efficiently, quickly, and effectively attract attention to secure assistance as and when required. Properly used visual distress signals help rescuers locate vessels in difficulty when searching and can prevent minor emergencies from becoming much more severe. Regulations regarding visual and other distress signals vary depending on your country of origin. However, the following are all required on vessels originating and operating in US waters and are as valid as any in providing maximum safety to those on board. The regulations stipulate that vessels must carry at least three devices for signalling during the day and three for use at night. 

 

TYPES OF VISUAL DISTRESS SIGNALS

Most visual distress signals fall into two categories: pyrotechnic and non-pyrotechnic. Provided each vessel carries three for nighttime and three for daytime use, any combination of these is permitted. 

 

PYROTECHNIC DEVICES

Any pyrotechnic devices on board must be Coast Guard-approved, in good working condition, and stowed in such a way as to be readily accessible when required. Most commonly found in the form of flares, pyrotechnic devices are combustion-based products that burn with bright, colourful light, generating heat and smoke. It should be noted that pyrotechnic devices have an expiration date, which is generally no more than 42 months from their date of manufacture. If no regulations exist regarding the use of pyrotechnic devices as distress signals, using only those within their expiry date is still recommended. Malfunctions or failure to ignite are not common but are more likely with out-of-date devices. Expired flares are not necessarily useless and may be carried as backups, but they will not count towards any legally required quota. 

  • Red flares: Aerial or hand-held. Red flares can be used anytime, but they are most effective at night or during periods of restricted visibility, such as haze or fog.  
  • Orange smoke: Floating or hand-held. Both are excellent signalling devices, especially on clear days. Ideally, no more than light to moderate winds will be blowing, as stronger ones tend to suppress the smoke or disperse it rapidly, making them less effective. 
  • Launchers: for parachute flares or aerial red meteors 

A suitable glove must be worn to hold a flare by hand, and it is important to be aware of the direction of the wind. The device should be kept downwind of the vessel to prevent choking and toxic smoke inhalation. 

 

NON-PYROTECHNIC DEVICES

Because no single signalling device can be effective in all conditions, it is recommended that vessels carry several types, including: 

Daytime use:

  • Orange distress flag: At least 3 x 3ft (92 x 92cm) in dimension, an orange distress flag has a black square and ball on a bright orange background. It is considered a day signal and is highly effective in direct sunlight. It should be waved or hoisted for maximum effect.
  • Sea-marking Dye: This strong dye turns the water a bright colour to attract attention from above. The dye dissipates rapidly, so these devices should only be deployed when aircraft are heard.
  • Signal mirrors: Using mirrors to flash distress signals is a tried-and-tested method of drawing attention but of limited use in low light or dense cloud cover. 

 

Nighttime use: 

  • SOS distress light: With no expiry date and a piercingly bright LED light that can be seen up to ten nautical miles away for 60 hours, a modern SOS distress light is a non-negotiable addition to any vessel. This device will only flash the SOS sequence and cannot be used for other purposes. 

An ordinary flashlight is insufficient for distress signalling, as most cannot flash automatically, and even those with that option do not possess enough candle power to be effective over long distances. 

 

WHEN AND HOW TO USE VISUAL DISTRESS SIGNALS

As the name suggests, visual distress signals are designed to be seen and are of little to no use if this is not the case. Only employ short-lived distress signals like flares when you are confident they can be seen or you hear other vessels and vehicles nearby. Common sense and good judgment are essential in emergencies, and the deliberate, effective use of visual distress signals is part of this.

 

Pyrotechnic devices, advantages and disadvantages

Pyrotechnic distress devices are the most popular among many mariners and are a potentially life-saving resource in times of need. 

Advantages:

  • Cost: Smaller pyrotechnic devices are particularly affordable 
  • Ease of use: Hand-held flares are easy to ignite and can be ignited even in bad weather conditions due to their potent chemical reaction. 
  • Visibility at day and night: Although the smoke will be less visible from a distance at night, the incredible brightness of the flame will be visible over great distances. 
  • Universal recognition: Coloured flares are a universally recognised signal of distress that should bring help no matter where you are. 

 

Disadvantages:

  • Single-use: All pyrotechnic distress devices are essentially fireworks by any other name. Once lit, they burn until they are done, and that’s their end. A flare cannot be extinguished if ignited accidentally or under false pretences.
  • Potential for injury and property damage: The intense flame produced by most hand-held pyrotechnic devices burns exceptionally hot. They require protective equipment to hold and create not just the desired bright light and smoke but also ash and slag that can cause severe burns. Debris falling from a lit flare can ignite other materials and exacerbate the situation if mishandled. 
  • Launching devices are a kind of firearm: The immense explosive power that propels this type of distress signal into the air is extremely dangerous if misused. The force of a launched flare leaving the device can easily cause severe injury or even death. Aiming the device poorly can result in its remaining on the vessel, which will burn just as hotly and brightly as a hand-held flare, risking fires and chaos on board. 
  • Duration of signal: Most flares have either five or fifteen-minute durations once ignited.

 

Non-pyrotechnic devices, advantages and disadvantages

Advantages:

  • Multi-use: Battery-operated signalling devices can be used repeatedly and turned on and off as required
  • Duration of signal: Premium SOS distress lights can remain activated for up to 60 hours 

 

Disadvantages:

  • Cost: High-quality signalling devices can be expensive
  • Daytime use: Although not entirely without use during the daytime, LED lights are much harder to see in bright conditions 

 

RESPONDING TO VISUAL DISTRESS SIGNALS

It is an unwritten rule of the sea that any vessel will come to the aid of another in distress. Upon spotting any visual distress signal (or hearing one via your VHF radio), you must notify the nearest Coast Guard before anything else. The internationally recognised emergency channels are as follows: 

  • CB – Channel 9 
  • VHF marine radio – Channel 16 (156.8 MHz) 

Once you have alerted the authorities, it is vital to assess what, if any, assistance you can provide on the scene. You must only attempt to assist any stricken vessel if you can do so without endangering yourself. 

 

WHAT OTHER SAFETY EQUIPMENT IS REQUIRED ON A YACHT?

Although attracting attention using visual distress signals and other devices is a crucial capability on board any seafaring vessel, there are other items of safety equipment it is the responsibility (either legally or morally) of any yacht owner to have in place, including:

  • Sufficient numbers of quality life jackets
  • Fire safety equipment (extinguishers for various types of fire, fire blankets, sand buckets)
  • Comprehensive first-aid kit
  • Kill cord (to disable the engines if the captain falls ill and is no longer in control of the vessel)
  • Dredging pumps and manual bailing equipment
  • Life rafts

 

FINAL THOUGHTS

The crucial thing to take away from this article is that no single device can provide the solution under all conditions. It is safer and more practical to carry a range of visual distress signal devices and deploy them as the circumstances dictate. Above all, when faced with a situation that demands a signalling device, think carefully about which will best serve your purpose. Wasting single-use, short-lived devices in panic is counter-productive and can mean the difference between salvation and further difficulties. It is recommended that all mariners take safety courses and train in the proper use of signalling devices.
